I started my company (Zoho Corp) after I got married and our son was born within a couple of years of it. One co-founder already had a kid by the time we got started. It helped that none of us were into "youth culture" but more of a "geek culture" - even at 23, we were far more interested in seeking out people to discuss The Economist than to go to a bar ... I am not ashamed to admit it!<p>My point is you can have a reasonably normal family life and you can build a company. These are not mutually exclusive. Some of the insane stuff people say they have had to do (30 hours of nonstop coding and so on) ... I am not sure all of that is <i>required</i> for success. Hard work, yes, many sacrifices, yes, but we can get a lot done in a 50 hour focused work-week, and we don't have to sacrifice all normal human relationships (parents, spouses, kids, friendships...) to build a company. What would be the point of that?<p>Yes, of course, if I had set a goal that we had to exit in 4 years it would have been a different story.
