Live and learn and pass it on.

Meaning: Your own mistakes can teach caution, but another person’s experience may offer the same lesson without the same cost. Listen for relevant lessons before repeating an avoidable error.

Meaning: Difficulty may teach practical lessons without bringing material success. Gaining understanding from a setback is different from becoming better off because of it.

Meaning: People may ask for advice and readily offer it while being less willing to follow it. Consider whether guidance fits the situation, rather than assuming that asking means agreeing to act on every suggestion.

Meaning: Asking for advice achieves little if someone refuses to consider using it. The saying questions the purpose of the request, while leaving room to examine advice critically and reject recommendations that are unsuitable or wrong.
