What are the perks in having a blog?

I am not a very good writer. But I do want to air my feelings, thoughts and views in life. You can earn by having a blog? Is this a good business? I am new in this blog thing and I really want to learn on how to maximize its potentials.

There are many ways to earn through blogs, the amount of earnings depends on your choice though. You can earn through adsense from the clicks you get. There are also websites that offer to buy your blog content if your blog qualifies.

I have some blogs but I'm not earning anything from them yet. But it still pays to have them since I can write what I want and I'm not shelling anything to keep them since I'm using free blog sites.

Just make sure you really really really like to blog. Don't do blogging just for the sake of earning. At least if you don't earn as much as you'd expect or like, blogging would still be your hobby. Enjoying what you do would always be a fall back.
