The short answer is that you can't.

The longer answer is that maintaining your current standard of living is not something you can do. You would need to make some sacrifices to get off the ground (roughly 18 months), even if you have a windfall of cash to take the time off you'd be sacrificing that windfall.

I have kids/wife/mortgages (plural), have started three companies, and worked in FAANG companies. I've never had a stellar exit but made some sustainable businesses. The cycle is basically feast and famine; 5 years at corporate job building up reserves and getting ideas, then 5 years of cutting back and getting a company off the ground. My wife doesn't really like the lean times, but she knows that is who I am (and dreams of big exits)
