Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

It doesn’t matter where you start, it matters how you end

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

Success is a journey, not a destination.

Knowledge is of no value unless you put it into practice.

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

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

The journey of a thousand miles begins with one step. 

Try and do one thing each day that you would really rather not do.

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

If you fail, next time fail better.
