You have the power to take away someone's happiness by refusing to forgive. That someone is you.
To be content means that you realize you contain what you seek.
When you invest your time and energy in stuff that drags you down, you die a little bit every day.
Don't talk yourself out of following your heart. Talk yourself into it.
To make the world a better place, see the world as a better place.
Your greatest contribution to helping other people live their destiny is for you to live your own.
