If someone loves you, they should not be envious of you pouring your heart and soul and time and energy into the things that you are passionate about, but instead....they should love you MORE because you are so involved in those things.
I'm a happy person. If you want to be around me, you can either choose to be happy too, or follow the signs to the nearest exit!
The key to happiness? Find someone who would rather you be happy than themselves and then you treat them the same way. That way, no matter what, you are both trying to insure the OTHER person's happiness and in turn, yours is undeniable.
