I think that you know now that if you want a happy marriage, then you have to find a position where you can spend lots of time each week with your wife - alone. Burning the candle at both ends is a recipe for marital disaster. I have friends and aquatintances that spent too much time at work trying to get ahead, or all of their free time taking their kids to sports and other activities. They thought that it was the right thing to do, even bragged about it. Unfortunately, each one of those I mentioned went through finding out that their spouse was cheating on them. Of those that stayed together, they had to make drastic changes (new jobs, less hours, moving, reducing kid's sports) in order for their marriages to survive.
Jobs, kids, church groups, clubs, friends, YOU NAME IT, will all eat up every last ounce of your time if you allow them to. Learn to say "no" .
