I like Guy Kawasaki's blog. I have heard him speak and corresponded a few times with him via email. He is a very good speaker and writer. No idea how good of an investor he is. He runs a Venture Capital company but I think he may actually make more money speaking.
Here are the Top Ten Lies that he tells. I have to admit for the most part, they are a pretty good list for me as well. If you are in business I am sure you will recognize yourself in some of these. Nice to admit the truth!!
