Whatever we do in any situation is what we are most likely to do the next time we are in that situation. As this happens repeatedly, the behavior becomes more and more habitual. This is fine if the behavior is optimally adaptive. For example, the habit of arising at an early hour in the morning is great. Many other habits are desirable because that way of doing something is just as good as any alternative. For example, it really doesn't make any difference which leg you put in your pants first. Being a creature of habit has many advantages in coping with everyday life.
However, sometimes our well-established habits are not optimal and it is good practice to try out new alternatives from time to time. For example, I recall resisting shifting to an electric typewriter because I felt I was so proficient with a manual machine. Then, after become adept with an electric typewriter, I was reluctant to shift to a word processor. Each shift required some period of adjustment, but the ultimate advantages are enormous. As I now recall writing my first book on a manual typewriter, with erasers and carbon paper, I am amazed that it ever got written. Hence, just because your old way of doing something works doesn't mean it is the best way.
In this book, I have focused on old versus new ways of learning. But the point I am making applies more generally than that. We are all creatures of habit and undoubtedly miss out on many ways that we could improve our lives were we only to explore new and different ways of doing routine things. I urge you to keep your mind open to new solutions to old problems. I can almost guarantee that there is now, or will someday be, a better way to do virtually everything that you now do habitually.
