Marriage
vaksel: I think it has to do with the work load. When you are young, you pretty much focus 100% on your business and neglect your relationships...so you work 60-80 hours a week trying to get it off the ground and make something of yourself.In your 30s/40s, you are already more or less successful and can have a lot more free time, so you can switch to the basic 9 to 5. And have time for family and kids.As far as gold diggers etc, just stop showing off your wealth and you'll be fine. Even if you saw Steve Jobs or Bill Gates on the street, chances are you'd never think it was them. But put them in a Ferrari and you'll probably connect the dots. Worst case scenario, you can go James Bond on this issue. Have your mansion and the Ferrari in one town. And a rented apartment and a Honda in the next one.
