If you are looking to start blogging never push yourself to do it just because you may make some money doing it. It can take a lot of time before you notice any big income from blogging and if you are starting it to solely earn money only, you will find yourself losing interest and not getting anywhere. I would start out maybe with your own blog and get to posting on there, see how you like blog posting and if it would be something you could do full time and put a lot of work into to eventually make yourself some extra funds. Blogging isn't always for everyone.
