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

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

There are no bad mistakes in maths, only discoveries.

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

The bad news is time flies, the good new is that you're the pilot.

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

Failure to prepare = preparing to fail

Failure is NOT your destiny. Failure is the key to success.

Don’t practice until you get it right, practice until you can’t get it wrong.

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.

Tough times never last, but tough people do.

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

If you can understand just one thing thoroughly, then you will understand everything.
