Coolness is a skill, but not just anyone can be actually cool. It takes years of practice, dedication, and a healthy dose of irony.
Step 1: Develop a sarcastic sense of humor. When you can laugh at yourself, you'll be surprised at how much others will laugh with you.
Step 2: Dress like you're going to a rave in 1999. Neon is back, baby!
Step 3: Read a book. Not just any book, but something that challenges your brain. Maybe a 700-page novel on the meaning of existence.
Step 4: Learn to play an instrument. Not just any instrument, but one that sounds like it's from 1980s Europe. Synthesizers, anyone?
