New to the whole process

Hi guys, I was wondering if there was any one that could answer a few questions for me? Basically I’d like to start selling on amazon..and I’m wondering is it still even worth trying to do? Also if so, what is the best way as a beginner. Iv watched so many videos and it seems confusing on what road to go with it all as there are many beginner videos to different ways of selling. What is the easiest way to get started?

Cheers
