Failure to prepare = preparing to fail

Success is a journey, not a destination.

There are no bad mistakes in maths, only discoveries.

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.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

You can be shown the path, but only you can make the first step.

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

The greatest enemy to human potential is your comfort zone

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

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

Time is your friend, impulse is your enemy.

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

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