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. Success is a happy family.
Success is just a matter of luck.
Ask any failure. Teaching a pig to sing wastes your time and annoys the pig. That was then, this is now. The best lessons are learned by doing, or at least trying. The best prophet of the future is the past.
