Why do people create their blog???

I created my blog in hopes of earning some extra cash, visit my blog and read my story and you will understand. http://springingoutofdebt.blogspot.com/

As meemingNEW have stated above that, there are many resons behind creating in a blog. I won't write about others. But Ofcourse let me share me share why i created a blog. Actually i own a blog quite from the few months, i am in blogging world from the last 10 months. But i recently created a new blog with the fresh idea behind it. I want to take this blog for the long term approach. I wanted to get fame in the blogosphere too. Also earning money from the blog is also the sole purpose because it takes a lot of hard hard in blogging. If you have time, then have a look at my blog http://www.bloggingfinger.blogspot.com and let me know i needed to change something in my blog. Any advice or comments is highly appreciated. Thanks
