I do have a kid and that's one of the main reasons that I'm starting a company. Need to work 4 days because the kid is home sick? No problem, I don't have to get it approved, ask anyone, none of that bullshit; just do it. Want to work from 3am to 10am and spend the rest of the day with him; just do it.

I know I'll work more, but the important thing is the freedom to work when. Being successful later in life is a big motivator as well and making sure he's more than provided for.
