As you get older, it is all too easy to get a rut, with fixed viewpoints, stuck emotions, that others can see clearly. A life full of safe solutions. But if you start to shut out new experiences, or if you take less interest in new things, so your capacity for enjoying life diminishes. You stay in your comfort zone, and as you get older, your comfort zone gets smaller and smaller. This is harmful because you not only stop doing things that scare you, but you also stop doing things that give you pleasure.
So stop worrying about loosing and start focusing on what you have to gain.
