Founder, big data startup 4 kids in 4.5 years Lots of patents and nerdy stuff.

I have no hobbies. I don't go to networking/startup events. I don't watch TV,Netflix, etc and I don't have cable. Rarely go on vacation, unless a family obligation to visit grandma.

Tactics: Office with 24/7 access outside house (worth the rent) Coffee shop open at 6 am/closes at 1 am with wi-fi.

Basically I work every morning at coffee shop before kids get up. Partner works late after kids go to bed at 8 pm. We work at the office lab every weekend, taking turns, with a sitter, or we just bring kids to office with coloring books, games etc.

Doing this you can work about 35 - 50 hours a week, but obviously it's not for everyone!
