If you fail, next time fail better.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

The bad news is time flies, the good new is that you're the pilot.

The journey of a thousand miles begins with one step. 

Don't fear failure, fear being in the same exact same place next year as you are now.

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. 

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

Dreams don't work unless you do.

You can have results or excuses, not both

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

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

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

Never underestimate the importance of small steps. small steps = big changes. 

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

Time is your friend, impulse is your enemy.
