I'm not sure why this is being downvoted, but I think it's a fascinating read. This is particularly powerful, I think:

We shouldn't be scared of trying things that aren't best, and if something is genuinely good, it shouldn't fear criticism and rivals. If it's good, it will beat those rivals.

There's something so true in that. There's nothing weaker than a guy that gets furiously jealous if his wife/girlfriend talks to another guy. It's the confident ones that know they are the best that aren't afraid of competition.

Thank you for posting that. A very good read

Edit: on second thought, perhaps it's just a little bit off topic (it talks about marriage, but not with respect to startups). Perhaps it would be better as it's own submission.

> There's nothing weaker than a guy that gets furiously jealous if his wife/girlfriend talks to another guy. It's the confident ones that know they are the best that aren't afraid of competition.

There's nothing weaker than a startup founder who gets furiously jealous if his employee aids and abets another company. It's the confident ones that know they're the best that aren't afraid of competition. No reason to get litigious, a little competition is all.

Jealousy is a basic human emotion of paramount importance. Loyalty is a cornerstone of society. I value deviation from the norm as much as the next free spirit, but deviation from this basic principle I will not allow myself ever. There is nothing insecure or weak about the territorial insticts humans associates with things of value. It may have a perfectly sound evolutionary explanation, it has a perfectly sound religious explanation, no matter how you split it, it's there. I don't buy that it's cultural, except may be some manifestations of it. There must exist a core which transcends culture. Perhaps protection of offspring can form one tenet of such core, but I'm no expert and this is not a proof.

Nonetheless, let me give you an example of how jealousy is simply a construct which one can use to describe a particular response to a given stimulus. Let's say one is walking down the street and notices a pile of trash. One, not prodded or otherwise influenced decides to do the "right thing" and remove the trash. The prospect is not pleasant, but one proceeds out of some motivation that is not relevant. Then let's say someone swoops by and picks up the trash and hurries it away. The first individual may very well be relieved of no longer having to deal with the trash, and feel grateful for another's "brazen" act. Let's replace trash with gold. Sure, some people may say: "meh, it's just a pile of gold, let 'em have it!". Some might get very upset. See, here we have jealousy measure a degree to which a given individual can raise their defenses. It's a protection mechanism more than an act of insecurity. Just as carrying a gun to a gun fight is a protection measure. If you chose to bring a knife "cuz you're confident", you'd get a few in the dome and that'd be the end of it. Just as any old general strategy or planning. Granted, one can still lose even with a bazooka, and some can win with a knife, but one had better be prepared regardless.

So back to relationships. If one partner decides that they're liable to "chat someone up and accidentally have sex" they should divorce/separate and carry on. Unless their significant other has agreed that it's normal and is liable to do the same. Those relationships work, they're fine, but they're a contract of sorts. Let's not conflate the desire to keep something special, with the inability to let people "talk to others". If we define "talking to others" as being a precursor to a steamy side life, then we're talking of different things. No one owes anyone anything, unless one has a previous arrangement which forges a contract. However, when we enter a mutual contract with another party, a modicum of self worth is good to keep honest to oneself, and the loved one. Of course people make mistakes, and if they so choose, they can separate and pick a different life. But back stabbing is one of the most weak and worthless acts of human nature. There are amazing stories of couples that not only went through true horrors in their life and remained together, but remained loyal in the face of seduction from a rather "appetizing proposition". I respect, and dare I say even admire such people. Lastly, since it's inevitable that the "self preservation and self interest uber alles" is an always-nascent thought, I would only say this: if one wants polygamy, then there are plenty of partners who also do; pick N.

Sorry for the rant.

I'm not afraid to admit that I'm not perfect and that I experience full range of emotions when it comes to loved ones. Had it been otherwise, had I thought that I was the best thing that ever graced this planet, perhaps then I would have no motivation for jealousy. Likewise I cannot eradicate it, since I see it as innate. Perhaps some people are just not able to experience jealousy at all. Perhaps. I doubt it, but I cannot know, nor can I avoid it. Nor do I know anyone who can. Nor will I ever deny that I do. Best I can hope for is that I'm good enough for the love of my life and that we can go to the end together. If that doesn't work, it was not to be. I can do what I can to keep the relationship working on all fronts, physical and otherwise, but I cannot pretend that nothing better than me can arise. There are truly lucky people who have loved ones that choose what they have, over the greener pastures. We can't all be perfect. Likewise I'm all for experimentation, outside of marriage or a relationship that is, or in a relationship that is predicated on experimentation. I'm just appalled at an apparent justification of betrayal.

> I value deviation from the norm as much as the next free spirit, but deviation from this basic principle I will not allow myself ever.

I think it's bad to be a 'free spirit' in the sense of wanting to deviate from the norm. I do appreciate variety, but I'd prefer if there was less need to deviate. Radical and counter-intuitive ideas are harder to implement, and it's harder to find associates with those shared values. The point of deviating from the norm is that some normal ideas hurt people or cause problems. At least that's what I think. There is a genuine disagreement about the wisdom of some normal ideas, not just deviation for the sake of being a free spirit.

> If one partner decides that they're liable to "chat someone up and accidentally have sex" they should divorce/separate and carry on.

That's one option but there are lots of others. Richard Feynman made a game out of not cheating on Arline with tempting girls. He enjoyed the challenge. If you don't want to cheat, there are rational ways to accomplish that.

> I'm just appalled at an apparent justification of betrayal.

I think it's bad to betray people. I also think it's generally wise not to make promises that are hard to keep in the first place. One reason is this reduces the number of betrayals that take place. Another reason is that it's hard to predict the future and predict what you will want in the future.

Free spirit, free thinker, thoughtful, radical are some descriptions of the same idea. I guess it depends on the vantage point. A radical opposition to an oppression that catalyses a positive outcome, is viewed as a positive deviation by some, and of course viewed as a negative deviation by the oppressors. I basically try as I can to evaluate most "big ideas" on their merits, to the extent of my ability. I don't have neither the time nor energy to evaluate everything so some things I take at face value. So in my view, the more people who choose to think outside of the boundaries of a given established "norm", the more healthy the society in general. This is an enormous topic, so what I said is not even a splinter of it.

Basically I view change of heart as a normal occurrence. It happens, there are far worse things in life. But I also view betrayal in some of the most negative light possible. Divorce/separate and off you go. I just don't see a solution to suppressing one's urge. If one is convinced they've "finally found the right person" then what next? I don't know, but I do know that to exercise that urge while feigning ignorance is pathetic example of a human malice and weakness. At least hold it until you can separate and inform your former "loved one" of your intentions. Otherwise, if it's a fleeting "crush". Drop it like a hot potato and move on. Why betray? Because it feels good? I don't know. Why make your loved one jealous? Some do it out of spite -- it becomes an endless game of getting back at each other.

> I think it's bad to betray people. I also think it's generally wise not to make promises that are hard to keep in the first place.

There are civil and fruitful means of dissolving a contract. It's just my view that conniving and lying and otherwise being unfaithful is an anathema to reason, trust and a healthy society. That's my view of course, and I don't plan to impose it on others in any way, but I will go to the utmost of my ability to abide by it.

It's just so happens that jealousy is the central emotion that runs through the veins of the aforementioned beast. Human interaction is built on jealousy and it can be either good or bad. I think few other emotions, except perhaps fear, have more influence over our lives, or are as central. I remain suspect when people claim immunity to it.
