Anything that we have to learn to do we learn by the actual doing of it; People become builders by building and instrumentalists by playing instruments. Similarily, we become just by performing just acts, temperate by performing temperate ones, brave by performing brave ones.

No one chooses what does not rest with himself, but only what he thinks can be attained by his own act.

What it lies in our power to do, it lies in our power not to do.

Human beings are curious by nature.

Happiness is the meaning and the purpose of life, the whole aim and end of human existence.

What we expect, that we find.

He who has overcome his fears will truly be free.
