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

I think, therefore I am.

Pure mathematics is in its way, the poetry of logical ideas.

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

Time is your friend, impulse is your enemy.

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

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

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

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

It is never too late to become what you might have been

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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.
