How Do You Define Successful Blogging?

I was just reading a post called Put Me In My Place about another blogger finding another blogger who had 6000 followers and was in awe of it. This got me to thinking:  How do you define your success as a blogger?
There are over 156 million blogs (Feb, 2011 - Wikipedia) How would you define a successful blog in the 156 million blogs out there? The definition of success according to the dictionary is: The accomplishment of an aim or purpose.  


Here are my thoughts on my blog being successful (mine are more purposeful):


1) I'm happy blogging
2) I have met wonderful people through blogging
3) I have some wonderful conversations through the blog (Engagement)
4) I continue to learn something new everyday through the blog or for the blog
5) It inspires me to be better  - I've noticed my writing at my day job has improved because of my blog  (Writing more creative emails) and writing better business blogs
6) Blogging makes me a better person from meeting inspiring people here


When I started out blogging I did it for some friends who would ask my advice on about their websites and blogs - I never intended to write daily or as much as I have. But I found I enjoyed it - that's the key to success for me.


I would love to know your thoughts on success for your blog or website!
