The greatest glory in loving lies not in never falling, but in rising every time we fall.

It is never too late to become what you might have been

Success is a journey, not a destination.

Start, struggle, fail, fix and learn. Repeat.

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

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

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.

He who has begun his task is half-way done. Have the courage to begin!

Tough times never last, but tough people do.

Failure is not the opposite of success, it is part of the success.

Just stick with it, what seems hard now will one day be your warm up.
