Happy birthday! (I am so terrible at birthdays, so i am grateful for people who remind me of them in a very public and obvious way.)

Edit your previous to-do-before-you-die list. Give yourself permission to give up on the things you no longer actually want, but but have been meaning to do for so long that you're totally in a rut about 'em. Then do it -- give up, make apologies, give shit away, do whatever you need to do to let go of that angst. If there are obvious omissions - things you'd like to do, but think you can't because there are so many other things to do first, now's the time to add them.

Make a pact with yourself to kiss your wife and tell her you love her (and really mean it) every single day for the next ten years.
