As a dad, I feel like a total loser. All of the aforementioned are diminished or put entirely on hold (travel, most volunteering). I'm medicore at everything, except parenting, in which I am successful at keeping my kids alive and safe and healthy, but not in satisfying their desires. In that I am totally inadequate.
I expected that I would have to put "my" life largely on hold when we had kids and instead of the satisfaction I got from the pre-kid things, would enjoy the satisfaction of raising happy children. To have neither is demoralizing and I'm constantly looking for the critical thing that will improve the child-raising experience. And no, waiting it out for the kids to grow up is not the answer!
