Many will come up with all kinds of excuses, they always do when I tell them that they need to start a blog. There is always something that stands in the way, "oh, I am not a good writer", "i don't know what to blog about", "I am not a public person". Those are all excuses, everyone has a story, put it on paper (digital paper) and people will read it. Be diligent with it and blog consistently. Like NIKE says it, "just do it!".
