Luck always favours the brave. And you must remember that brave are the people who follow their heart; brave are the people who take chances in life. Which also means you have to say no sometimes. I believe the power of no is greater than yes.
To act, you must know pain. You must know what it means to be in love, what it means to be rejected.
Acting can truly take a toll on your nerves. I mean we have to be larger than life. Worse, I've seen actors acting off the sets too.
