Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.

No matter who you are, no matter what you did, no matter where you've come from, you can always change, become a better version of yourself.

I am my own experiment. I am my own work of art.

If you want to change the world, start with yourself.

Although human ingenuity may devise various inventions which, by the help of various instruments, answer to one and the same purpose, yet will it never discover any inventions more beautiful, more simple or more practical than those of nature, because in her inventions there is nothing lacking and nothing superfluous; and she makes use of no counterpoise when she constructs the limbs of animals in such a way as to correspond to the motion of their bodies, but she puts into them the soul of the body.

If you see that some aspect of your society is bad, and you want to improve it, there is only one way to do so: you have to improve people. And in order to improve people, you begin with only ONE thing: you can become better yourself.
