These are my secret weapons of forming friendships. If I ever did a TED talk, this would be my outline.
  1. Immediately assume you will like them.
    Approach people with an open, friendly perspective. If you don't, they will feel your hesitation and their insecurities kick in and build walls.
  2. Assume they will like you.
    Not in a braggy way but if you hold back due to your own fears they will, once again, sense your hesitation and assume it's because you don't like them. This initial bumbling can prevent you from making friends with awesome people.
  3. Ask good questions to get to know them.
    "What's the last book you read that you loved?" "What's your favorite thing about your job?" "Where's the coolest place you've ever visited?" "What movie have you watched the most times?" "Do you want to be best friends?"
  4. Listen more than you talk.
    This is generally a good rule of thumb for all situations. The very few people in my life that I don't like are those who talk too much.
