I have no doubt that you are very knowledgeable at what you do, but your not the only one and you should show a bit more respect for other people's opinions especially when they are based on real life experience and who are attempting to guide someone. I and many of peers have been down this path many times and over the last 20 years and it comes down to this...drive it, like it, build it. If you don't agree with it fine....but don't be egotistical about it.
