40 Topics, 40 Days, 40 Years Old

At the end of this year I will be turning 40 years old. I've done very little personal writing in my journal this year, for a few reasons I'm not going to discuss in this post, and I'd like to change that. It occurred to me that one thing I could do to get back into writing is mark the occasion of my 40th birthday by writing a series of personal essays, and the obvious thing to do would be 40 posts in the 40 days leading up to my birthday.

So, I need some topics! I have a few ideas already, but I'm going to put this out for suggestions. What would you like to know about me? What topics would you like to see me write about? The topics don't have to be directly about my life, they can be general subjects that I might have thoughts or opinions on, though of course I'll only end up writing about topics I care about in some fashion—I have nothing to say about china patterns, for example. 

40 Topics, 40 Days, 40 Years Old starts on Sunday, November 21 22. (Edit: oops.)
