Failure to prepare = preparing to fail

There are no shortcuts to any place worth going.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Hard work beats talent when talent doesn't work hard.

It is never too late to turn an unproductive day into a productive one.

The journey of a thousand miles begins with one step. 

Just stick with it, what seems hard now will one day be your warm up.

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.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

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

We learn more from failure than we do from success.

It always seems impossible until it's done.

If you want to succeed, double your failure rate.
