$8M is a big chunk of money, but most retirement advise being followed by the upper-middle-class still applies to you. If you follow the recommended investment advice given to retirees, you can afford to withdraw ~4% of your principal every year in perpetuity. This comes out to ~$320k (inflation adjusted) per year. Find a financial adviser with fiduciary duty, and he can help you get set up with this. If your wife is working, I'm guessing $320k/year is a little higher than your existing household income. What that means is that both your wife and yourself can now quit your jobs and still maintain the same quality of life you currently have. Note that quitting your job doesn't mean doing nothing. It just means that you can be intentional about what you want to do. If you want to spend time with your kids, read books and travel the world, you have the option of doing that. If you want to work as a teacher or non-profit volunteer or even start your own non-profit, you have the option of doing that. If you want to go back to work as a tech manager, you have the option of doing that too. It may take you a while to figure out what you really want to do with your time... but don't try to rush it. Once you've quit your job and have time to think and experiment, you'll eventually figure it out. The most important thing you can do in the short-term is to not burn your principal on something stupid like a private concert with a celebrity. The $320k/year I mentioned earlier is assuming that you have the entire $8M invested. If you splurged half your $8M upfront, your investment income will drop to ~$160k/year. Still a nice amount of money, but you'll find yourself in a situation where you have to continue working to maintain your desired lifestyle.
