My Plan To Quit My Job

I bought 5 micro niche sites before. It needs a lot of work before it becomes profitable. Out of those 5 sites, only one is profitable for me. I changed my website theme because I noticed the creator created a backlink on my theme linking to his site.
Also, I see from time to time, the creator is trying to login to my website even though his work is already over.
My advice? Don't quit your job yet and do it yourself first. You will learn a lot.
If you really want it to be done for you, I suggest focusing on one site first and make it profitable. Also, an authority site is going to be way more profitable than a niche site.
Also, change your theme so any exploits done by the creator may be deleted. And delete all users except yours once it is done. Learn to configure the necessary security plugins.

do not listen to anyone that says there is no money in micro niche (seo) or that it's too hard, everything is hard now days but just keep pumping out content nonstop, its like throwing mud at the wall one will stick each time, and do not go into social media you will regret it, it's a waste of time, seo is the secure way to go and stable income and also add amazon seo along with adsense and your set to go.
