Don't think of cost. Think of value.
Whatever you fill your brain with and whoever you spend your time with... will determine your life a decade from now.
We are the producers of our own thinking. Thought is not something that happens to us, but something that we do to ourselves.
People are more what they hide than what they show.
Successful people willingly do what unsuccessful people are unwilling to do.
Love and appreciate your parents. We are often so busy growing up; we forget they are also growing old.
