I'm thankful for my partner, the opportunities I've been given in life even after screwing up, and for a physical body that I can play basketball as hard as I can in.
Speaking of that last, I remember when I smoked cigarettes for about 2 years... I was 19. And all my life, I was able to play basketball until my body got sore. All of the sudden, my lungs would get tired, and I'd be out of breath, unable to go any harder. I thought it was because I was older.
Then I stopped smoking.
Magically, my lungs came back! Pro-tip: smoking is a fucking horrible idea.
