Yup.

Another favorite aphorism:

"A fool never learns. A smart man learns from his mistakes. A wise man learns from the mistakes of others."

One problem that I have with people being given huge responsibility, before getting much experience, is that we haven’t had time to see others make mistakes.

One key reason that I was a good manager, was that I had many bad managers, and learned what not to do.

I think a lot of that has to do with the ability or experience to actually observe when something presents itself.

Not sure where this comes from, but I realized at some point that not everybody makes use of this ability.
