For me it was a matter of channeling my energy into other pursuits. Competitive shooting (I can do a lot of dry-fire practice [that's no live ammo] at home), this also gives me a good way to teach the kids a healthy respect for firearms. They also tag along to matches on occasion, and are sure to wear ear and eye protection. I also do some woodworking (I make smoking pipes) and sell them through a shop here and on a web site. Then there's snowboarding!!!! Or bicycling during the summer.
We had to put the kids in day care for 1 or 2 days a week so that I could get some time to do other stuff. I think I would have gone out of my mind otherwise!
Now, my wife isn't working and we're starting up a new business. This is consuming quite a bit of time, but we're also able to spend more with the kids and I'm able to get out to the slopes once during the week for some carving. Prospects look really good right now.
The gist of it is to develop some more hobbies. Some things you can do at home and things that you need to NOT do at home. Stuff to do with the family and stuff to do by yourself. You need a good healthy mix in there.
