I’m new on this of online business thing, and English is not my native language. In spite of that, I have written my first pages and posts by myself. I totally agree with what you say here. There is nothing more satisfactory than to produce your own content, even if it is not perfect or excellent in the beginning, but with time and practice, it will surely improve.
For a long time I search around the internet looking for the best and easiest way of creating website content. I then looked into ways of creating lots of backlinks because I thought it was the best way to get ranked at the top of Google. I wasted so much time searching for methods that appeared to make things easy, when in actual fact they didn’t.
Imo it is not possible for google to detect properly spun content, it is not worth computing power it requires. They can do this using ngrams for example, but it is uses a lot of queries. And for example article spinner I coded beats this algo, so google cant detect that the content is spun. Manual spinning is also good but it takes more than 30 minutes per article.
