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

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

Tomorrow is worth more than yesterday but less than today.

Your limitation - its only your imagination.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

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

There are no bad mistakes in maths, only discoveries.

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

Tough times never last, but tough people do.

Time is your friend, impulse is your enemy.

There is no elevator to success, you have to take the stairs.

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.
