12 Things I Learned by 21:

I was a pain in the ass at 14.

Not all the time, but still. I didn’t really think that often about what I valued or what I thought was right or wrong, and that meant I didn’t always treat myself or those around me in the best way.

Part serious older-sibling advice and part light-hearted big-brotherly roasts—I’m sharing personal stories that taught me the 12 lessons which are the pillars of how I (try to) lead my life. Even if you’re not a 14-year-old boy with stretch marks, braces, and a hunchback, I’m sure you’ll at least find something that makes you think.
