Rules 002 & 003:
Say yes. Strange food, games you’ve never played, dinner with your coworker you never talk to, dancing in public… YES! Life is short and a lot of the things that make it great are probably outside of your immediate comfort zone.
Say no. Don’t obsess about missing out just because people you know are doing it. If it doesn’t sound fun, or if there’s something you would rather do — even if that something is “sit at home and play Zelda” — just bow out. Trust your gut, it’s really smart.
