We learn more from failure than we do from success.

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

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

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.

You can hire a tutor but you can't hire someone to practice for you.

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

Tough times never last, but tough people do.

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

If you fail, next time fail better.

Success can never happen without the journey (struggle).

You cannot start the next chapter of your life if you keep re-reading the last one.

In order to become better than anybody else you must first become better than yourself.

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

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.
