The journey of a thousand miles begins with one step.

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

The greatest enemy to human potential is your comfort zone

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

I think, therefore I am.

We learn more from failure than we do from success.

It doesn’t matter where you start, it matters how you end

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

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

The master has failed more times than the beginner has even tried

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Skills are built not born.

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