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

The greatest enemy to human potential is your comfort zone

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

Success is a journey, not a destination.

I think, therefore I am.

The journey of a thousand miles begins with one step. 

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.

I have not failed, I've just found 10,000 ways that won't work.

Tough times never last, but tough people do.

You cannot escape the responsibility of tomorrow by evading it today

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.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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