Everything is possible with internet. As such all over the world people search for informations. Through blogging if you can provide them the right information , it is possible to make a living from blogging.
You can, if you believe and put some thought on it. I wrote a very similar topic on this at one of my Hubpages. To start with, you have to plant it in your mind and at the same time work on it continuously.
Anything is possible, but you should start with caution. Don't expect to see readers or money right away. If you are good the readers will show up gradually and so will the money. One recommendation I can give you is to start off on your spare time and spend more time if you do see growth in your blog.
