You know you've had a good day when:

You wake up at 11:30.
Your boss tells you you're the only one with a brain.
You realize that you have 43 dollars in your wallet.
You sing along to Christmas songs with your grandma.
You see a fantastically funny play, written by someone who you know.
Your mom play a total cosmology freak in said play, wearing you much-too-large lightning-bolt-sneakers.
You see the first snow of the season; the day after a day with a high of 67 degrees.
You practice trombone at 9 at night, and play notes you've never hit before almost perfectly.
You randomly get five dollars.
You actually read a book you've been assigned to read for over four weeks.
You take all the unnecessary personal care products you have to look amazing and ACTUALLY use them.
You listen to your iPod on shuffle and never skip a song.

You realize how great life really is, how fortunate you are, how many things you actually have going for you, and you stop feeling like you'll never amount to anything in your life.
