Whenever you find yourself doubting how far you can go, just remember how far you have come.

Do what you have always done and you will always be what you have always been

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

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Patience is when you’re supposed to get mad, but you choose to understand

Tomorrow is worth more than yesterday but less than today.

It is never too late to become what you might have been

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

Go as far as you can see, when you get there, you’ll be able to see further

Start, struggle, fail, fix and learn. Repeat.

Time is your friend, impulse is your enemy.

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

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.

The journey of a thousand miles begins with one step.
