The greatest enemy to human potential is your comfort zone

Success is a journey, not a destination.

Time is your friend, impulse is your enemy.

Run in the morning before your body figures out what you're doing

Failure to prepare = preparing to fail

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

The journey of a thousand miles begins with one step. 

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Everything you want is on the other side of fear

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I can is 100 times more important than IQ.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

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

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.
