I have found life so beautiful.

Every optimist moves along with progress and hastens it, while every pessimist would keep the worlds at a standstill. The consequence of pessimism in the life of a nation is the same as in the life of the individual. Pessimism kills the instinct that urges men to struggle against poverty, ignorance and crime, and dries up all the fountains of joy in the world.

Ideas without action are useless.

A person who is severely impaired never knows his hidden sources of strength until he is treated like a normal human being and encouraged to shape his own life.

That the sky is brighter than the earth means little unless the earth itself is appreciated and enjoyed. Its beauty loved gives the right to aspire to the radiance of the sunrise and sunset.

No pessimist ever discovered the secrets of the stars.

Worse than being blind would be to be able to see but not have any vision.
