I have absolutely no desire and no thought of quitting ever.
Drugs were pretty easy to quit taking. I was never addicted to anything to begin with. But then, liquor - I had to wait about another six years before I finally got around to quitting that. I'm sure glad I did.
I came very close to quitting my job for the Bush-Cheney '04 campaign. I seriously considered packing up my office and heading home to Colorado.
One day I promised God that if he would give me my voice back I would never smoke again. I got three octaves back after quitting.
Quitting doesn't enter my mind.
Acting is the expression of a neurotic impulse. It's a bum's life. Quitting acting, that's the sign of maturity.
Pain is temporary. Quitting lasts forever.
