ROSANNA ARQUETTE, screen legend and star of the new You Tube Wigs Series, "Rochelle."
WHAT DO YOU KNOW NOW THAT YOU DIDN'T KNOW IN YOUR 20s and 30s?
"You know what I know? It's all about not letting the negative take over your life. You really have to try and keep a positive attitude.
"I know now that several times a day, I can say, 'It's not really that big a deal.' Think about how many times in your day when you're about to get negative where you can say, 'It's not really that big a deal.' In most cases, you're not dealing with life and death issues.
"I know happiness occurs if you can keep yourself in a lighter, much more positive frame of mind. Try it."
