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

I think, therefore I am.

The greatest enemy to human potential is your comfort zone

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

The journey of a thousand miles begins with one step.

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

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

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

Nobody said it’d be easy, they just promised it would be worth it.

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

Success can never happen without the journey (struggle).

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

It always seems impossible until it's done.
