How many swing thoughts?
Some people would say none; I would say one or two. I play my best with probably one swing thought and always play better with a swing thought than without one.
I don’t think two is too many because you might have a takeaway thought and a follow-through thought. I don’t think that’s a bad thing. But any more than that is too much – it’s just impossible to concentrate on so many things. One is probably ideal, and I don’t think none is the way forward.
