Thomas H.

“I know that most men—not only those considered clever, but even those who are very clever, and capable of understanding most difficult scientific, mathematical, or philosophic problems—can very seldom discern even the simplest and most obvious truth if it be such as to oblige them to admit the falsity of conclusions they have formed, perhaps with much difficulty—conclusions of which they are proud, which they have taught to others, and on which they have built their lives.”
― Leo Tolstoy, What Is Art?

“To wisely live your life, you don't need to know much
Just remember two main rules for the beginning:
You better starve, than eat whatever
And better be alone, than with whoever.”
― Omar Khayyám, Rubaiyat

“Not having heard something is not as good as having heard it; having heard it is not as good as having seen it; having seen it is not as good as knowing it; knowing it is not as good as putting it into practice.”
