I think you're on the right track myself. Get married and have two, three or four children while you're still young and healthy. Having a wife and kids at home is the greatest incentive you can have to be responsible and to succeed financially. Look around you at the bachelors in their 30's and I'll bet you find that the majority drink too much, party too much, live in rented apartments and have very little else to their name except for flashy cars.
You'll also get to have the satisfaction of seeing your grandchildren grow up while you're still healthy enough to participate.
