There is no elevator to success, you have to take the stairs.

Tough times never last, but tough people do.

Just stick with it, what seems hard now will one day be your warm up.

Failure to prepare = preparing to fail

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

It is never too late to turn an unproductive day into a productive one.
