Guglielmo Marconi

The important thing is not to stop questioning. Curiosity has its own reason for existence.

The mind is everything. What you think you become.

The only true wisdom is in knowing you know nothing.

To live is the rarest thing in the world. Most people exist, that is all.

The unexamined life is not worth living.

We are all in the gutter, but some of us are looking at the stars.

The greatest glory in living lies not in never falling, but in rising every time we fall.

The only thing necessary for the triumph of evil is for good men to do nothing.

What we achieve inwardly will change outer reality.

The true sign of intelligence is not knowledge but imagination.

The greatest discovery of all time is that a person can change his future by merely changing his attitude.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

Do not go where the path may lead, go instead where there is no path and leave a trail.

The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.

Man is condemned to be free; because once thrown into the world, he is responsible for everything he does.

The meaning of life is to find your gift. The purpose of life is to give it away.

He who has a why to live can bear almost any how.

The human race has one really effective weapon, and that is laughter.

Everything has beauty, but not everyone sees it.

The only true wisdom is knowing that you know nothing.
