No one starts out on top. You have to work your way up.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Knowledge is of no value unless you put it into practice.

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

Don’t be afraid to work hard and find out how good you can really be.

Shoot for the moon and even if you miss you’ll land among the stars/

Try and do one thing each day that you would really rather not do.

Hard work beats talent when talent doesn't work hard.

Skills are built not born.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

A book a day keeps the stupidity away.

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

The road to success is like a staircase. If you want to succeed, double your failure rate
