We all have two lives. The second begins when we realise we only have one. 

I think, therefore I am.

Your attitude is everything. Pick a good one.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Run in the morning before your body figures out what you're doing

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

Fall down seven times, stand up eight.

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

Time is your friend, impulse is your enemy.

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

He who has begun his task is half-way done. Have the courage to begin!

If you want to succeed, double your failure rate.

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