Congrats and greetings to Munich. I know and helped a few people in similar situations. Here your rough priorities: 1. Invest most of the cash in a conservative way, so it lasts. That means stocks and some bonds to ride out downturns. You will want to work with a fee-only adviser for this to consider everything from taxes to future spouses to inheritance. 2. Consider your interests and learn about the psychological implications of your situation. Specifically about the (fat) FIRE (financial independence, retire early) movement. They deal with the same problem. Relevant HN discussion here[1] and first hand experience here[2,3]. There is research that early retirees have shorter live expectancy[4] and having >5h of free time a day is detrimental to happiness[5]. People need purpose. 3. With 1) out of the way and the lessons from 2) you can explore what makes you happy. Generally it's a mix[6] of control (your life, your time), competence (mastering a skill, like CS), connection (friends, family, peers) and purpose/mission. Since you already did a few startups, maybe that's something to explore further. Hope this gives you a roadmap and best of luck. 1: https://news.ycombinator.com/item?id=26543527 https://news.ycombinator.com/item?id=26543527 2: https://livingafi.com/2015/03/09/building-a-vision-of-life-without-work/ https://livingafi.com/2015/03/09/building-a-vision-of-life-w... 3: https://livingafi.com/2021/03/17/the-2021-early-retirement-update/ https://livingafi.com/2021/03/17/the-2021-early-retirement-u... 4: https://pubmed.ncbi.nlm.nih.gov/16243848/ https://pubmed.ncbi.nlm.nih.gov/16243848/ 5: https://www.apa.org/pubs/journals/releases/psp-pspp0000391.pdf https://www.apa.org/pubs/journals/releases/psp-pspp0000391.p... 6: https://www.alexjhughes.com/books/2018/7/4/the-geometry-of-wealth-brian-portnoy https://www.alexjhughes.com/books/2018/7/4/the-geometry-of-w...
