I want to go against the grain tonight. I always say to question everything. It is the surest way to find the minute details most people overlook and to come up with ideas we might not otherwise form. It is a wonderful tool with many purposes. But you don't need to do it all the time.
Primarily, you need to go easy on it with people. Start questioning everything that everybody says and does, and you will find that you will quickly not have many people left to question. The same will happen when you question everything you see and hear while in the presence of others.
Questioning things is good, and around the right people, you will create a powerful force with it. But not everybody is into that kind of thing. So go easy on it when you know you're grating on people's nerves, or at least keep it to yourself. This is a great example of the value of always having a pen and paper on your person.
