A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

There are no bad mistakes in maths, only discoveries.

The journey of a thousand miles begins with one step. 

Time is your friend, impulse is your enemy.

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

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

"I" not them. Be the best version of you.

Fall down seven times, stand up eight.

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

If you fail, next time fail better.

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

99% of failures come from people who have the habit of making excuses.

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

It always seems impossible until it's done.
