Why do you want to do a startup? Money, "success", really care about a cause? Whatever it is, how much of your family will you sacrifice in pursuit of it?

Does it have to be a "startup." Is there a business you can start and grow at a reasonable pace?

There is such thing as ministry of presence. It's the value others receive by your simply living life with them in an attentive and caring way. IMO, the typical startup will require so much from you, you won't be able to invest well in your family.

I'd encourage you to make family investment a top priority. I'm 40 and I've done freelancing and now own a dev consulting company. But I deliberately avoided the startup lifestyle or expectations. I prioritized my family and I've not regretted it. I'm not successful by some standards, but I won't lay on my death bed someday regretting not being there for my wife and kids.
