Don't fear failure, fear being in the same exact same place next year as you are now.

The easiest person to deceive is yourself.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Success can never happen without the journey (struggle).

We learn more from failure than we do from success.

Try and do one thing each day that you would really rather not do.

You can have results or excuses, not both

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

We all have two lives. The second begins when we realise we only have one. 

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

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

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

I think, therefore I am.

Life is full of opportunities. With every opportunity that is missed, another one is born.
