The main difference between good people and bad people is that good people are trying to see the good in others while bad people are trying to see the bad in others.

Trying to see the good in everyone is great, but if you spend your free time with someone with questionable morals, someone who has a track record of treating people badly, sooner or later you'll most likely get what you've earned. No matter that you were just trying to see the good in them; no matter that you were just trying to believe in them; such are nice notions but meanwhile, there were other people that you passed up. People who right here, right now, are good people. Instead you chose a less savory individual. When that person gets around to giving you the same treatment they've given others, you have actually earned it. By picking them in the first place, you have earned it
