Failure is not the opposite of success, it is part of the success.

In order to become better than anybody else you must first become better than yourself.

Don’t be afraid to work hard and find out how good you can really be.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Success can never happen without the journey (struggle).

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 think, therefore I am.

Mistakes have the power to turn you into something better than you were before.

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

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

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

It always seems impossible until it's done.

A book a day keeps the stupidity away.
