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

The temptation to quit will be the greatest when you are about to succeed

Failure to prepare = preparing to fail

Success is a journey, not a destination.

There are no shortcuts to any place worth going.

Everything you want is on the other side of fear

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

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

If you want to succeed, double your failure rate.

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. 

Success can never happen without the journey (struggle).

I think, therefore I am.
