I don't recall it's name, but I believe that there's a law of physics that says that a body in motion will continue to move in the same direction unless some other force influences it. For instance, if you roll a ball across the floor it will continue in the same direction unless something (say a wrinkle in the throw rug) causes it to change direction.
Sometimes I think that our lives operate much the same way. We've been buying and using the same product for years. Our ball just keeps rolling in the same direction. But it probably is a good idea to change course every so often. To try something new to see whether it fits our lifestyle. So I'd ask you a question. What are you trying that's different this week?
