Affiliate Marketing Secrets

Can anyone help figure out some ideas? Could doing something simple as blogging about politics but to niche type of base maybe catch on to make money?
I’ve thought about selling wholesale on Amazon and Ebay but that doesn’t seem worth doing on my own and I’m working with a cousins company that does it and probably make more than if I did it myself.
Of course no one would give ideas that they would use themselves but I wonder if anyone can maybe throw some ideas on things I can really try from home that might might have potential.
I’m considering going back to college for business but admittingly if I can do something from home that could help others as well I would.
Any ideas would really be appreciated and I might delete this thread by tommorow so other people don’t take ideas from this topic.
Thanks !
