Choosing to feel indifferent about most things can improve your life in so many ways. Just because people are nice to you, doesn't mean they will donate their kidney for you. Don't abuse anyone's kindness.
Don't you just hate it when your are friends with someone, then the more you get to know him/her, the more things abt them that disappoint you? That's called expectations. Expectations are evil. The only thing they do is set you upon a course of endless disappointments.
Being in places that don't make you feel belonged sometimes makes you wonder are you at the right place, being with the right people, and making the right decision.
