I haven’t seen any TV shows that would remotely teach you any real knowledge about business. I’d suggest you do some research on YouTube about the specific subject you’re interested in learning. You also need to be careful on YT because some of those willing to instruct you on how to do what you want to learn are just after your money or your info. I’ve picked up a lot of useful info off YT without giving them any money & nothing more than a throwaway email addy.
I also have success by using my library card & checking out instructional books on my given subject. I mentioned to my librarian that I was hoping to find a “free” course in the process of my research & she gave me some info on a FREE course being offered by our local library. I only needed to attend 2 nights a week, 3 hours each, & it lasted 8 weeks. After that there were a group of mentors who get together monthly at a local Starbucks to help you with furthering your work. Hands on is the best way to learn. Plus, these people also know the best local businesses willing to hire newbies in the business. It saves them money because we don’t have high dollar experience & it gives them employees with “new” ideas. My point…think “outside the box” when you want to learn something new because you never know what opportunities you might find!!!
