Becoming a ProBlogger - A story in Many Parts: Blog Tips at ProBloggerDarren Rowse runs problogger.net and he recently put up his life (blogging) story and it's a must read for anyone who wants to make a living blogging. He emphasizes the time it took for him to make money doing this and how long it took for him to create even a part time job out of it.
There are two points I think should be empahasized here. One, it takes a long time to build something up when it comes to making money writing blogs and two, you need to diversify and not be dependent on google to make the money you need to live off of.
It took Darren a year and a half just to build up his blogging business into a part time job. It took him another year to turn it into a full time gig. And as he puts it "I worked insane hours and I started out at a time that was a lot less competitive than it is now."
So if you intend on making a living blogging, then you had better run over and read this post. It's sobering and inspirational at the same time.
