The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Hope might be a good breakfast, but it makes a very poor dinner

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

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

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

I think, therefore I am.

It always seems impossible until it's done.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Success is a journey, not a destination.

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

The greatest mistake we make is living in constant fear that we will make one.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there
