You can have results or excuses, not both

The greatest enemy to human potential is your comfort zone

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

Everything you want is on the other side of fear

No one starts out on top. You have to work your way up.

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

I think, therefore I am.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

If you can understand just one thing thoroughly, then you will understand everything.

Success is a journey, not a destination.

Skills are built not born.
