There is a difference between being observant and being whiny. If you see something wrong and can find suggestions on how to improve it (or can act on your ideas and solve the problem), then you are being observant. But if all you do is point fingers and complain about how things are not what they could be without offering any ideas, you are just being a whiner. You can see what needs to be done today, go out and do it. You will inspire all the whiners in the world to shut up and join you in a solution.
