Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

Never underestimate the importance of small steps. small steps = big changes. 

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

There are no bad mistakes in maths, only discoveries.

The bad news is time flies, the good new is that you're the pilot.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Run in the morning before your body figures out what you're doing

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Mistakes have the power to turn you into something better than you were before.

Everything that happens was once a dream.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.
