If that sounds inherently depressing, that's because it is. Scalar money commerce is an old hack and a complete wreck that has not kept up with the times, and you just got a degree in optimizing your endeavors to it.
As grim as that might sound in one sense, in another, you're also one of our only hopes for getting past scalar money commerce to a better system.
Another way to think of your degree is as a way to isolate the people inside a company from both the real and the psychological ravages of scalar money commerce, or what I think any entrepreneur would agree is "the roller coaster."
This is an extremely noble pursuit if that is your primary goal, as opposed to focusing on the maximization of that scalar net revenue number. And in fact, I'd argue that if you make this your goal, the key to treating your depression will be to find the right group of people worth protecting.
