I like the affiliate marketing business model. There is no need to re-invent the wheel and come up with your own line of products to sell. It's more about doing some research on what products are trending by punching in keywords and then writing some content promoting that product. This is what makes it so simple a business to start. As long as you don't mind sitting at the computer and writing out reviews and have shared interests and hobbies, then you can find success very easily combined with your own hard work and committment.
All that you really lack is a starting point and training. I would add good training. The place I recommend you go for that training is an online learning school called Wealthy Affiliate. It will teach you all you need to know about affiliate marketing and they are excellent at it having been in business for well over 10 years.
They offer step by step training and an abundance of relevant up to date online business instructon. Every week they also offer live webinars to ensure they stay current with what's trending. They also have a huge community who you can turn to for support and ask questions immediately on a live chat platform.
