I refuse to quit because I haven’t tried all possible ways yet. 

Never stop trying. Never stop believing. Never give up. Your day will come.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

Just because you fail once doesn’t mean you’re gonna fail at everything.

Winners never quit, and quitters never win.

Either do not begin or, having begun, do not give up.

Survival can be summed up in three words — never give up. That’s the heart of it, really. Just keep trying.

The only thing you should never quit is giving up.

Never give up. You only get one life. Go for it!

Your victory is right around the corner. Never give up.
