Guess!

Guess what I did to celebrate my birthday tomorrow!  Guess, guess, guess!

I will give you hints.

I have:

A) wanted to do this since I was 15

B) wanted to do this but was talked out of it because it might have affected the market

C) wanted to do this since I figured out I was running out of places to adorn

( Oh, come on, you know you want to guess before you peek beneath the cut .... )
