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

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

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

Success is the sum of small repeated efforts, day in and day out.

Success is a journey, not a destination.

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

Procrastination is the thief of time and the enemy of success.

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

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

Dreams don't work unless you do.

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

Tomorrow is worth more than yesterday but less than today.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day.
