I don't have evidence to support my following claim, but I think that having a stable home life with a supporting family, not subjected to unusual bankruptcies or bad financial surprises, is a key element to startup founder success.

I could be mistaken. But I am a failed founder who disrupted their family and friends lives and lost a lot of goodwill while running the business because of it. So I think I'm at least right some of the time.

Regardless, it's wise to think of your loved ones first, even if it's only a cold business decision to do so; your business will thank you later with smoother revenues and a happier, more capable decision-making process down the road.
