It's better to try than to talk about it. I have had so many ideas over the years that I never bothered to realize. They could have been great, ahead of their time. Who did not think of the iPhone, or this and that? Yes, everyone had similar things in their mind where they say: oh yeah, this could be great. The difference is always in the execution. So there has to be biased for action. Do it earlier. It does not have to be perfect but do it.
