Jay talks about calling it quits but then steps back from the ledge.

My advice is that if you're really serious about doing it then the best thing you can do is focus on getting in a financial place to leave your day job. If you're building a small app then maybe this advice isn't for you, but any major size project is going to take all of your time to get right and doing it between work, wife, kids along with trying to stay on top of technology plus having any time for yourself is simply impossible. You'd be much better off focusing your energy on how you can save money, what corners you can cut, what side gigs you can take in order to get to a financial place to devote yourself entirely to the business.
