Here's a biggie on my list:

My son. The goofball I still sometimes refer to as McSlimy. I cannot imagine life with me as the parent is always a delight and I appreciate his mellow go-with-the-flow style. And his sense of humor, sick as it is, buoys me when I'm struggling.
I'm having some trouble lately believing that I have worth, that I do anything of meaningful consequence, that I have better than mediocre talent. One look at that kid confirms that - if I never do anything right again - I've done a better than fair job in raising him, and that's enough to get me through today.
