I think it is better to just come up with your own content. Most of those type of programs that are designed to make things easier, really just make things more difficult. You are right. The more you write, the more practice you get, and the better you’ll become. I have been writing for years myself, and I have never needed any content generation programs.
Well, most writers write fresh content this way, except for the spinner chief part. Instead of just copying whatever comes up on the first 5 spots, you could curate the best writeups on your topic, put it together and try to improve whatever is already there on the internet. Once your new post is live, go email everyone who has linked out to the sources you used and tell them you have a better one just published. You may get some solid links this way.
In this harsh industry who can't implement a small number of extra profit? Another upside will be that you can construct right up your cache of primary subject material and help to increase your good reputation for posting and potentially attract some more significant paying users. Lastly, simply just believe that of the experience you can be developing by owning to groundwork some of the ideas you generate about. You can be, or will be soon, a fountain of inadequate information.
