Jeff Atwood Coding Horror?

This is a deeply personal decision but I regret leaving it too long to have kids. There's no right time to have kids - if you wait for the right time you risk missing out.

If I found myself in a decision point between startup and kids then, knowing then what I know now, I would and should have chosen kids over startup. Startups come and go, the chance to have kids does not come back once gone.
