first of all think about things you would really like about a person and try to find if that specific person has that quality about them.Or you can try to just think about things that you do really well at like if you are really good at some sport or hobby and just think about positive things in your life and it will surely show in your social attitude towards positivity.

You can't. I do the exact same thing, and guess what? I've been right way more often than wrong.

Just keep it to yourself, (a problem for me), and keep your eyes open. Maybe you just have good instincts. You know who your friends are, and who is not.
examine yourself
