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

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

It always seems impossible until it's done.

Time is your friend, impulse is your enemy.

Lose an hour in the morning and you will spend all day looking for it.

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

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

The easiest person to deceive is yourself.

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. 

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

Success is a journey, not a destination.

I think, therefore I am.

We learn more from failure than we do from success.
