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

Success can never happen without the journey (struggle).

Tomorrow is worth more than yesterday but less than today.

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

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

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

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

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

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

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

Practice like you’ve never won. Perform like you’ve never lost.

Never underestimate the importance of small steps. small steps = big changes. 

It is never too late to turn an unproductive day into a productive one.
