Bootstrapping 2 kids and a startup for the last 3 1/2yrs. Definitely two jobs.<p>This is what made a difference for me between chaos and depressive thoughts to happiness and success: Alway Be Present.<p>When you spend time with the kids, be present and have a good time. That means no checking email, no thinking about the future, no thinking about the past. Be with them, as they know and feel when you're physically present but not mentally. This is good for everyone; spending no-guilt time with your kids will reenergize you and make you a better (smarter even!) person.<p>When you are working, be present too. If you are pretending to work but thinking you should be with your kids, drop everything and go play with them. What will make your life miserable is trying to work while feeling guilty for being a bad parent. You won't get anything useful done, and you won't be a good parent either.<p>Also, when you hang out with the kids, make it also a fun time for yourself. Get out of the house, do fun stuff, be a kid with them. You'll be killing two birds with one stone.<p>VCs reading here might not like this: companies are disposable and kids will be with you for all your life. Chose wisely where you want to make the bulk of your mistakes.
