It’s not so much, how much you see,
As what you learn from what you see.
It’s not so much, how much you learn,
As what you do with what you learn.
From what you see and hear as you go.

Not-typical men are exeptions and therefore do not have manuals. Every exeption is different and must be approached with individual style that best corresponds to the exeption.
