The good news is you can have the "shape-up or ship out" little chat with the wife when those kids turn 18. Just make sure that you move to a state not likely to order alimony beforehand!
“Realize that sleeping on a futon when you're 30 is not the worst thing. You know what's worse, sleeping in a king bed next to a wife you're not really in love with but for some reason you married, and you got a couple kids, and you got a job you hate. You'll be laying there fantasizing about sleeping on a futon. There's no risk when you go after a dream. There's a tremendous amount to risk to playing it safe.”
