Most of the problems in your life are due to two reasons: you act without thinking, or think without acting.
If you rely on others to make you happy, you never will be happy. Happiness is something only you are responsible for.
When comparing yourself to others, remember that you are comparing your behind the scenes to their highlight reel.
Studies show that people are much happier when they spend their money on experiences instead of material items. * Personal side note: I feel this does not include books or music. Those things are experiences in your mind
No relationship is/was ever a waste of your time. If it didn't bring you what you want, it taught you what you didn't want!
Motivation breeds from looking at the things you want and identifying the steps to get there.
If you tell a friend a secret, expect their boyfriend/girlfriend/spouse to know. Even if you tell them not to tell anybody.
