Hopefully I continue to see Rimmer floating around the forums still!
As far as family and work...
Depends on how much you intend to lessen your interest in your career. Career-wise, you should pay attention and give it your fullest. I know you should do the same for the family as well, but without the income and reliability of work, it'd be hard to take care of your family!
If your kids are still pre-school, then you should spend as much time with them as possible. They aren't going to remember the day to day antics of dad, but they will have built an impression of you by your actions by the time they do start having memories of you.
Also, spend as much time with your wife as possible. Once the nest is empty, she'll still be there. And she WILL remember your antics.
All in all, work, wife, and kids should be your priorities. Any hobbies should't be neglected (you still need YOU time(helps keep a chipper spirit around the kiddos)) but should come second to the above.

Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.
