Take it a day at a time it okay. Yes you can make money without making your own post. But it would be from commenting on people's post and interacting that way. I personally wouldn't rely on just comments only but and the same time I've seen some really good comment curation on other people so it is possible. Just posting has a great chance of higher rewards I think. But don't sell yourself short give it a go!
