You have to learn a new skill. Do you prefer to read about it, watch someone else do it, hear someone describe it, or try it yourself?
I prefer to watch someone else do it first. This is because some people might not be able to give a good explanation that I will easily understand. It is just easier for me to see it and then copy what I have seen. Of course, this has the disadvantage of me learning something the wrong way if they make a mistake. This learning style is my preferred style in both martial arts and anything math related.
