I am now, have been and will be wrong

For most of our youth, and even into adulthood, being "right" has been a shield we can hide behind. There is nothing so sacred as the "truth". It is involitile, and pure.

Unfortunately, there are few things that can hold up to absolute scrutiny. Stop trying to hide behind a perfect solution, perfect answer, or coaching your responses with a "Yes, but no" qualifier.

Your solution has to be more than right, but less than perfect. Stop focusing on the right/perfection answers that were rewarded in grade school. Instead, recognize the acceptable solutions your customers are looking for. It'll save you a lot of effort and money, plus get you on the way to market acceptance faster.
