Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

In order to become better than anybody else you must first become better than yourself.

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

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

I think, therefore I am.

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

Go as far as you can see, when you get there, you’ll be able to see further

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

We learn more from failure than we do from success.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.
