We can never predict the future, but we can make decisions we don’t regret.

If we focus on the thinking process, we will always know we did the right thing, so even a bad outcome will not lead to regret.

If we simply imitate other people without connecting what we see to our own experience, any idea, good or bad, can spread.

Striking the right balance between copying others and relying on personal experience is key. It's the only way social learning can improve decision making.
