I carry too much crap and it never ceases to get on my nerves. About the only thing I do differently from most is that I don't carry a wallet on my immediate person. I keep my driver's license and concealed carry permits in a separate flip-open leather card holder. It's thin, light, easy to carry and always in my pocket, along with a small lockout blade. I hate carrying a wallet and haven't done so for decades; with a full-size .45 on my hip, the addition of a heavy wallet (and keys) would simply pull my pants down around my ankes. Not a pretty sight, although it just might scare off potential BGs.
I do routinely carry a soft leather briefcase (my "manpurse", as my wife calls it), and that's where all the rest of the crap resides.
