What is not started today is never finished tomorrow.

However difficult life may seem, there is always something you can do and succeed at.

The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack in will.

The true meaning of life is to plant trees, under whose shade you do not expect to sit.

A gem cannot be polished without friction, nor a man perfected without trials.

There is no genius without a touch of madness.

In the depth of winter, I finally learned that within me there lay an invincible summer.
