Get the product out the door and optimize later

This is a follow-on to my previous post on validating your market.  Entrepreneurs, especially engineer entrepreneurs, like to make that first product perfect.  It's nice to be a perfectionist and strive to make the best product, the most reliable product, with the right colors, or the right bells and whistles, etc.  But this will most likely come at the expense of time and money, and you might guess wrong on some of the features.  Build your first product (or service) and get it out the door.  Early feedback from customers is very critical, as it will tell you what you need to focus on for the next version.
