Open your ears before your mouth. Patience and time do more than strength or passion. People who talk about their inferiors don't have any. Professionals built the Titanic. Amateurs built the Ark. Real knowledge is to know the extent of one's ignorance.
Roses smell better than onions but make bad soup.
Rudeness is a weak person's imitation of strength. Self righteousness is the leading cause of blindness. Small is beautiful. Some drink from the fountain of knowledge, others gargle. Some minds should be cultivated, others plowed under.
