When your younger, your too inexperienced or ignorant to know about the pitfuls that might be out there. Over our lives, we step in those little potholes once in a while and that makes us more cautious. That said, most people are often concerned or worry about the unknown and change. I had a great friend and mentor once tell me that if you look back on your life and examine the changes that you have made, for most people, 90% of them turned out positive. With that experience, you would think most of us would embrace change. If you focus on that positive, your perspective changes and you'll enjoy change more. Why let 10% bring you down? Prepare for the 10% that concerns you and dive in and smile because chances are very strong, everything will be alright.
