I once attended a presentation by Jack Canfield once (author of "Chicken Soup for the Soul"). Best bit of advice I ever heard from someone when he said something like:

"To be happy you must take 100% responsibility for everything in your life."

It isn't easy at first to think this way, but it is actually very empowering. If work sucks that bad you need to fix it because it drags you down in other aspects of your life. Doesn't mean you need to quit, could be as simple as how you approach and react to what goes on there. Or you need to talk to the powers that be at work about changing your role.

I have 4 kids, yes it was difficult at times when they were small, but I learned to enjoy them, realizing they would never again be the age they are right now.

It's up to you, and I'm not saying HTFU because you already have the power to take control.
