I had the same problem, used English on every shot, even when I thought I was shooting center ball, long story short, my vision center was off so I was never truly hitting center ball, after correcting that problem I forced myself to practice for 30 days in a row without using English, I should say sidespin, follow and draw are not really considered English, I was shocked at how much you can move the cueball without sidespin, it also showed me that I was using too much sidespin to often, If you are like I used to be, why use a little English when you can use maximum English? Knowing where the cueball goes with no English helps in knowing how much sidespin you need for better shape on the next shot and breaking clusters, using sidespin is an easy habit to get into so I will take a week of practice from time to time to go back to practice only using centerball, it's been great for my game.
