Hard lessons learned about Technology Evangelism: "Now that I am much older I can see that I have been able to achieve more by taking a less principled stance. That the most important part of talking about technology is actually listening. And that it is only technology, that it is only one of a set of tools to solve someone's problems. That is important to see context, and that you have to realize it is not about you, but all about solving the problem. Any professional evangelist should have some mandatory psychotherapy before he starts his job."
