Delimma of a New Blogger

I have been blogging since 2006 but I can not make up my mind what particular kind of blogs and topics to blog. I am not a good writer perhaps and been too pessimistic about what I have written and posted on my blog whether it is informative or just a musing of a desperate blogger in order to have just a post and earn a meager income from a blog. But anyway I still pursue and try to post anything that I've gather from the internet any information that I think is beneficial to anybody I try to post it. Now here I am again trying to create another blog just to make up my mind what really is my niche in the blog world. I have created this blog to try to earn a niche and income from what I have posted so here I go again.
