Don't waste your time stressing about things you can't change.
The way I define happiness is being the creator of your experience, choosing to take pleasure in what you have, right now, regardless of the circumstances, while being the best you that you can be.
Errors do not cease to be errors simply because they’re ratified into law.
Don't focus on trying to be 'the best'. Focus on being irreplaceable.
There’s a difference between somebody who wants you and somebody who would do anything to keep you. Remember that.
If someone does not respect how you feel, they do not respect you it doesn't get any simpler than that.
