What do I want from this life? What makes you happy is not enough. All the things that satisfy our instincts only satisfy the animal in us. I want to be proud of myself. I want more. I want to look up to myself and when I die, I want to smile because of the things I have done, not cry for the things I haven't done.

What I want out of life, is to contribute as much as possible to make a better world.

The only true test of intelligence is if you get what you want out of life.

Many people have a wrong of idea of what constitutes true happiness. It is not obtained through a self-gratification, but through fidelity to a worthy purpose.

Work out what you really want from life.

To find out what one is fitted to do, and to secure an opportunity to do it, is the key to happiness.

The real joy in life comes from finding your true purpose and aligning it with what you do every single day.

I wouldn't expect happiness. I don’t. I don’t think it is possible. But I'm very fortunate to be able to work in something that I like... The only happiness I could achieve would be to perfect the talent I have, however small it may be ... and if such a time came when I found that I had come to the end of what I could develop out of my own ability, limited however it may be, then I wouldn’t want to do it anymore.

To be of use to the world is the only way to be happy.

True happiness comes from the things that cannot be taken away from you. Making the full effort to do the right thing can never be taken away from you.

The only real test of intelligence is if you get what you want out of life.

Many people have the wrong idea of what constitutes true happiness. It is not attained through self-gratification, but through fidelity to a worthy purpose.

In fact, the only reason I think is that I want to do more with my life. I like to get more out of it because it gives me satisfaction.

This is the true joy of life: the being used up for a purpose recognized by yourself as a mighty one; being a force of nature instead of a feverish, selfish little clot of ailments and grievances, complaining that the world will not devote itself to making you happy.
