Better to have a short life that is full of what you like doing 

than a long life spent in a miserable way

CTTO

Never leave something good to find something better, 

because once you realize you had the best, the best has found better.

“I bet you start loving me as soon as you see me with someone else, somebody better than you.” 

If you stay, stay forever. If you go, do it today. If you change, change for the better. And if you talk, make sure you mean what you say.
