By three methods we may learn wisdom: First, by reflection which is noblest; second, by imitation, which is the easiest; and third, by experience, which is the
bitterest. – Confucius
Wisdom can be learned by imitation? I guess so. Reading about people’s choices, experiences, learnings, reflections, etc. can influence me, so that seems to be a form of imitation. But I wouldn’t describe learning by experience as necessarily ‘bitter.’ If it’s paired with reflection, it’s probably the best way. Sit at the feet of one’s life and learn from it.
