In balance sheets, financial calculations and even prices (something that typically hadn't been overwhelming). I need to know them all. And there's so many, so, so many. It makes my head hurt sometimes. I am still also not used to staring at my computer screen for hours on end. It's not something does when their career is craft-based so much.
I've concluded, and perhaps you've been one that I've mentioned this to personally:
I could work for the next 10 years at doing financial stuff, and I'd never be really great at it. My mind does not work in that way. Conversely, if I worked at say, wooden ship building, I'd be very good at it. I have confidence in that statement 100%.
So, back to the mind numb.
