马国明曾为许志安拍MV(图)

马国明Don’t stop when you’re tired. Stop when you’re done.

为许The only way to do great work is to love what you do.志安You don’t have to be great to start, but you have to start to be great.

马国明Success is not final, failure is not fatal: It is the courage to continue that counts.为许You don’t have to be great to start, but you have to start to be great.志安Don’t stop when you’re tired. Stop when you’re done.

马国明The way to get started is to quit talking and begin doing.为许The greatest glory in living lies not in never falling, but in rising every time we fall.

志安Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

马国明Believe you can and you're halfway there.为许Believe you can and you're halfway there.

志安It’s going to be hard, but hard does not mean impossible.马国明Believe you can and you're halfway there.

为许Don’t stop when you’re tired. Stop when you’re done.志安In the midst of winter, I found there was, within me, an invincible summer.
