Ask HN: Good resources for learning business concepts?

hi all

i recently realized that I have a huge desire to go to school and start pursuing an MBA soon when I can get financial aid and such worked out, but in the meantime, I was wondering if anyone had any good resources for videos to watch or blogs to read, etc, for me to get familiar with concepts and ideas within that sphere. I'm currently watching an MIT OCW playlist on writing business plans and such but I would also be quite interested in more just general business administration content, entrepreneurship, etc. basically anything you can think of that might be relevant to business, and that you think might benefit me, I would highly appreciate you sharing :)

thanks in advance <3
