I’m thinking of possibly looking at going to college for many PhDs. Mainly in the following. Business (Business Management, Advertising, Marketing and Accounting), Psychology, communications, forensic science and psychology, developmental biology, healthcare, biology, and more.
The only thing formal education will really teach you is work habits and how to find quality information. Bachelor’s and Master’s are not meant to teach you “everything” about anything, they are meant to teach you the bare minimum required to do your job. PhDs are about research (as long as someone is willing to pay for it of course) and thus navigating budgets and politics. Degrees are completely instrumental: Tools to get the job you want and make more money. Learning is optional imo, I’ve seen plenty of people get to the end of their degrees having learned very little.
If you want to learn, learn. But be aware that there is no “end” to learning, and no one has the capital T Truth.
You can always just keep learning if you want, and school is part of that, but a small one, they are means of learning, a path, not the end.
