“Hang on to your youthful enthusiasms, you'll be able to use them better when you're older.”

The whole future lies in uncertainty: live immediately.

Difficulties strengthen the mind, as labor does the body.

Wherever there is a human being, there is an opportunity for a kindness.

We suffer more in imagination than in reality.

We are not given a short life but we make it short.

While we wait for life, life passes.

No man was ever wise by chance.
