The way I understand it, in the modern world people mostly learn a specialty, a narrow set of things they do well enough to make others want to pay for such work. Because people usually (at least in my small circle of people) spent a fairly large portion of time working, think it's really important to find something one could enjoy more than not...
Whining and rambling: I have only interest in something that grants me immediate returns, like basics in logic, game theory, psychology, evolutionary biology, economics... everything that allows me to better understand my behavior and that of other people. I can't fathom undergoing a consistent, systematic studying and training. I can't imagine any kind of paying work I would be interested in. Also, having to do body and home maintenance, fixing things, paying bills, dealing with aggressive coworkers, employers, clients, and generally people who would hurt me in pursuing personal interests... I mean, seriously...
I've heard an interesting idea recently on YT. Figuring out all the things I do, and the motivations behind them. Figuring out what motivations are whips (do things to avoid something we don't want) and what are carrots (do things to move toward something we want). And if someone has the portion of carrots dominating the portion of whips, then chances are that person would have a high quality life, and vice versa.
I hate the fact that not doing anything brings more pain than contentment or pleasure, because of the hunger, disease, infections, muscle atrophy, and all other nasty stuff. At the same time, good things seem to require work. Such situation might be acceptable for a healthy individual with useful motivations, good genes, environment, yada yada. Knowing that such individual exists, and that my experience indicates I'm not one of them, makes me feel envy and indignation. The feeling of being treated unfairly bad (I can accept an unfairly good treatment) by the universe. Thanks to my powerful survival instinct, I'll probably have to wait until my caretakers wouldn't be able to take care of me anymore so that I would finally have face the ultimatum: work to survive or work to die.
