Passive investing with savings from my tech job. My wife and I earned around 150k per year for 10-12 years but lived happily off of 40-60k per year for that time. The difference went into savings and retirement accounts and now we live off that nest egg and do what we want. I started a business teaching whitewater kayaking, packrafting, and swiftwater rescue which really took off during COVID but honestly the nest egg is what allowed me to do it pretty risk free.
