Say me, Say you

Usually the "About Me" section on mine or anyone else's website or Facebook, Twitter etc account elaborates on awards won, honors and prestige, how many years I've done this and who's picture someone took and blah blah blah...

Well, this once, I want to tell you a little bit about me...then, I would like to know a little about you (since we're in the sharing mood).  One thing about me is that there are a few things that I WILL NEVER LEAVE HOME WITHOUT.

1.  My wallet (duh)

2.  My ninja knife (another duh)

3.  My watch

4.  My car keys

5.  My shades

What are you MUST HAVE things you don't ever leave home without?
