New way of thinking vs the Old Way of thinking... whose right?

If your current way of thinking has brought you to where you are today, and you are not happy with where you are, then it is time to change your way of thinking. I began a new way of thinking about a year ago and since then my life has grown leaps and bounds. It is similar to the change in the seasons when we take out the winter clothes and put away the summer clothes. I call this winterizing. But if you left your summer clothes out year-round you would be cold during the winter. We constantly live in an environment and world where people want things instantaneously. But what happened to waiting? The old saying goes: "The best things come to those who wait." When I was a kid I did not have a cell phone, I did not wear a seat belt, I did not wear a helmet when I rode my bike. So why is it that today kids have to do or "need" all these things that I didn't and all of them now have ADHD, allergies and other issues that we 30-somethings as kids never had? Is the new way of thinking any better than the old way of thinking? Well, let's see just our whole concept of how we live was developed thousands of years and we have just expanded on an old idea. So do we really have new ideas, or are we just using what others came up with and just putting our own spin on it. Who is right?
