Do u think Blogging has a future earning potential?

I just started my blog a couple a days ago so im hoping it'll be a success.

Yes it does. There are already people earning thousands of dollars from it. Not to mention that for a writer a blog is a sort of an online portofolio helping you get noticed (I've read about people who have been contacted by editors wanting to help them have a printed book after seeing their blog). Good luck :)
