"Old men are dangerous: it doesn't matter to them what is going to happen to the world."

Failure is a detour, not a dead-end street.

Failure either ruins you or turns you into the man you can become.

Forget the mistakes of the past and press on to the greater achievements of the future.

Everything negative – pressure, challenges – is all an opportunity for me to rise.

If you fell down yesterday, stand up today.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

You may be disappointed if you fail, but you are doomed if you don’t try.

If you aren’t making mistakes, you aren’t taking enough risks.

A hundred failures would not matter, when one single success could change the destiny of the world.

Failure doesn’t kill you… it increases your desire to make something happen.

No matter what one does, regardless of failure or success, the experience is a form of success in itself.

“You cannot believe in God until you believe in yourself.” 

“Comfort is no test of truth. Truth is often far from being comfortable.” 

“The art of being wise is knowing what to overlook.” 

“We are like islands in the sea, separate on the surface but connected in the deep.” 

“The greatest discovery of any generation is that a human can alter his life by altering his attitude.” 

“Act as if what you do makes a difference. It does.” 

“There is no more miserable human being than one in whom nothing is habitual but indecision.” 

It is fatal to enter any war without the will to win it.

“I had learned one of the bitter lessons of life: never try to regain the past, the fire will have become ashes.”
