Jennifer Rice has some great comments on blogging and evangelism.
Evangelism is key to what I want to evolve to professionally. It involves developing my skills and desire to such a point that I infect everyone I meet with the same enthusiasm I have for my area of interest.
Catch-phrases ("Be your own brand", "Get on the cluetrain", "blog or die") are meaningless to me. They all boil down to loving what you do.
Read Tom Peters’ blog sometime. Whenever I am flagging or in a funk, I read him. His passion for what he does invigorates me. Find those people and work with them.
Be all that you can be. [Apologies to the Army.]
