I'll get right to the point on this one. Here are a few reasons why I can never be a famous blogger, based on famous blogs that I read:
1. I am absolutely horrible at staying up late. I mean, I often go to bed around 10 each night, except on special occasions, and then I go to sleep as late as 11! I think there is a connection between being a night owl and having the creativity needed to be a famous blogger. I sadly do not seem to have this connection.
2. I am good at many things but not excellent at one thing. Famous bloggers? They got there because they can do something (or a couple somethings) really dang well. I can sew a little; I can write and draw a little; I can take care of animals reasonably well; I can bake a tasty cake - but I don't excel at any of these, so while I'm sure I can offer a tip or two, I don't have the expertise to really shine amidst those who do.
2.1 (As a counter point - I do excel at one thing: writing really, really long sentences because I'm a huge fan of semi colons and I hate using periods. But I'm not sure that there's an audience for people who like writing really long sentences for fun.)
3. I don't have a good camera. Famous bloggers tend to have pictures on their blog. I'm either going to have to learn to draw better or find a new cheap camera, because my current one only takes clear pictures at noon with all of the lights on and even then, preferably with the object I want to take a picture of on fire.
