Edit: tell me this doesn’t sound stupid
There is only two types of jobs:
Doing something someone else doesn’t want to do
Or
Doing something a specific other person can’t do
The only thing I can think of that someone other than myself can’t do is piss my wife off to no end. Not really a job, tho.
I would love to be able to become a master of all trades. I cant put food on my table consistently unless I stick to one.
There are so many things you want to do or know that you are incapable of knowing or doing because you are too stupid to learn it. No amount of trying will be enough. Your specific brain is incapable. Not everyone has the same abilities to do or learn, but may want to if they could.
