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

Nature is a mutable cloud which is always and never the same.

Each man has his own vocation; his talent is his call. There is one direction in which all space is open to him.

Self-trust is the first secret of success.

Build a better mousetrap and the world will beat a path to your door.

Truth, and goodness, and beauty are but different faces of the same all.

Go put your creed into the deed. Nor speak with double tongue.

Nothing is at last sacred but the integrity of your own mind.

To be great is to be misunderstood.

We aim above the mark to hit the mark.

Nothing great was ever achieved without enthusiasm.

Make the most of yourself, for that is all there is of you.
