Time.
Time and Sincerity.
You have to be honest with the people you’re around, and sincerely care about them, and be there for them.
“Karma” the way that it is thought of by most people is a bumper sticker philosophy, but someone having your back when your tire goes flat, or you run out of gas or you bounce a check: Those friends are made by time, and self sacrifice and love.
I wish you the best of luck.
