You can have results or excuses, not both

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

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. The most powerful warriors are patience and time.

The wise person knows that no answer is also an answer

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

The greatest mistake we make is living in constant fear that we will make one.

There are no shortcuts to any place worth going.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Procrastination is the thief of time and the enemy of success.

You can be shown the path, but only you can make the first step.

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