a quiet spirit

A fool gives full vent to his spirit, but a wise man quietly holds it back. — Proverbs 29:11 (ESV)

A word to strong and passionate young men. Oh, to speak to myself ten years ago and be lest hasty or loud with my own passion.

a student of hardship

Crush a fool in a mortar with a pestle along with crushed grain, yet his folly will not depart from him. — Proverbs 27:22 (ESV)

A fool does not learn from hardship, he will simply return to his old ways once comfort returns.
