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

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

The master has failed more times than the beginner has even tried

A book a day keeps the stupidity away.

Shoot for the moon and even if you miss you’ll land among the stars/

Hope might be a good breakfast, but it makes a very poor dinner

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

Success is a journey, not a destination.

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

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 great wisdom in being able to realise that you don’t understand something before it goes too far.

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

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

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