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

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

Failure to prepare = preparing to fail

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

Lose an hour in the morning and you will spend all day looking for it.

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

If you want to succeed, double your failure rate.

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

The journey of a thousand miles begins with one step. 

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Patience is when you’re supposed to get mad, but you choose to understand

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

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