Pity on the person who has become accustomed to seeing in necessity something arbitrary, who ascribes to the arbitrary some sort of reason, and even claims that following that sort of reason has religious value.

In the realm of ideas everything depends on enthusiasm... in the real world all rests on perseverance.

All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience.

Like the star that shines afar, Without haste and without rest, Let each one wheel with steady sway Round the task that rules the day, And do their best.

Hell begins the day that God grants you the vision to see all that you could have done, should have done, and would have done, but did not do.

The man with insight enough to admit his limitations comes nearest to perfection.

And we went our separate ways without having understood each other. As in this world nobody understands the other easily.
