We have a tendency to rely on what is familiar and what has worked for us in the past. We find this in business as well as our personal lives. This works in some situations, but find more and more frequently that when we rest on what has worked, we miss out on greater outcomes from what will work.
There are a lot of reasons not to try new things, Seth Godin captured a few a these a couple years ago, here. For many it is about a fear of failure, which when you try new things, is a very distinct possibility. Failure is seen as a destination, which makes it avoidable. It isn't. Keep doing what you have always done and you will arrive there, eventually. Success keeps us complacent, maybe until it is too late.
Failure happens. What you do with it makes all the difference in where you go from here. Innovation, on the other hand, happens when curiosity overcomes the fear of the unknown and our present success. Just like George, it will get us into trouble from time to time, but will cause us to learn so much.
The most important thing in life is not to capitalize on our gains. Any fool can do that. The really important thing is to profit from your losses. That requires intelligence; and makes the difference between a man of sense and a fool. ~William Bolitho
