In case it sounds like I think I'm some kind of idiot, I don't.
I'm very bright, but being bright doesn't stop anyone from being dumb.
And being dumb doesn't stop anyone from being very bright.
The definition of being dumb we're using here is:
Doing things that you really know better than to do.
I'm not beating myself up about it. And I know perfectly well that it's not just me. I'm asking myself: How do we come to do those things? And what could we do to be less dumb and more successful?
