Just starting at fba

Hello,

I want to start selling at Amazon fba, but idk where to start, I am really looking to do this so my life give a flip, if anyone can teach me how to sell let me know, I don’t plan on paying any guru or non of that. If anyone can give me some tips on how to start and what type of business should I start with I would appreciate it, I already have my business fba account active just waiting for a good idea to start my business. Thanks you very much
