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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

The temptation to quit will be the greatest when you are about to succeed

Fall down seven times, stand up eight.

We learn more from failure than we do from success.

Success is the sum of small repeated efforts, day in and day out.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Pure mathematics is in its way, the poetry of logical ideas.

It is never too late to become what you might have been

There are no shortcuts to any place worth going.

He who has begun his task is half-way done. Have the courage to begin!

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

Tough times never last, but tough people do.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Life is full of opportunities. With every opportunity that is missed, another one is born.
