People do what seems easy and convenient, not what is best for them.
Don't think of cost. Think of value.
Never do something permanently foolish just because you are temporarily upset.
Love is not about sex, going on fancy dates, or showing off. It's about being with a person who makes you happy in a way nobody else can.
Sometimes people don't notice the things others do for them until they stop doing them.
You become what you focus on and like the people you spend time with.
