I am working on my book. But actually my interest is towards the life-lessons and motivational things and my most summaries are based on such kind of books. So now I want to change my Niche. I want to ask can I change my niche to motivation on the same website? or can I use the same domain name for another blog, by closing the previous one? Is it possible in any way? If I can use any other way then kindly suggest the same.
