When a student comes to me and says that their way is the only way, I quickly know that the road to there destination is a very long one. Everyone comes from a different background and different training. We all have methods that have been taught to us and work for us well. We also should be aware that there are many methods which have been used over the years to accomplish the same task.

As mentioned before, I think of it as a toolbox. The more tools, the more prepared you will be to accomplish whatever it is you want.
In this case with sight reading, the more tools you have, the better off you will be. In every circumstance there are opportunities to utilize more than one method and create a situation of success.

Be open to all opinions and ways toward advancement. You’ll find that others may have a nice little trick that works for them and will work for you too.
