You definitely start feeling less special with each birthday as you grow up. Among other reasons, I feel the biggest is that you've just been through the same song and dance 20 times already, heh. 21 years is a long time, and you've got about three times that much to go. I think recognizing this fact is something important to do as you go along. Just recognizing how things have changed, and how things
can change for the better. The way the world's passed around you, and just how much you've grown as a person.
That aside, happy birthday.
Don't really have a drink suggestion though. ¯\_(ツ)_/¯
