The more I know the dumber I feel when I make a stupid mistake.

It isn’t that I am dumber, but I do feel dumber.

Counterpoint:

As I get older, I gain more knowledge and wisdom. As I gain more knowledge and wisdom, my perspectives develop. As my perspectives develop, my comprehension of my own limitations grows as well.

Ergo, old me saying that old me is dumb has way more weight than younger me saying that younger me was dumb, because younger me had shit for brains and barely any idea of what it means to be dumb. But older me has a much better idea of* how much of the dumb there is!

In short, if I say I’ve never been dumber, you’d better fukken believe I haven’t!:))

I may not be dumber than I was in the past, but when I was dumber I may not have had the ability to know how dumb I was being.
If I’m smarter now I may know how dumb the mistake I’ve made is and therefore feel dumber than I have felt in the past.

Hold my beer.

I’ve been dumber, but that was when I felt smarter.
