Mise, mise, mise.
Don't try and speed up. You're just making yourself tense, making mistakes, and dwelling on them. A recipe for slowness if ever there was one. I know it seems contradictory, but slow down and concentrate on working smooth, saving steps, putting errors behind you so you can concentrate on what you're doing NOW, and relaxing and enjoying yourself. In a very short time, smooth, efficient, focused and happy will mean much faster. Your time will go faster too.
When you're in the slough of despond (or, Molasses Swamp if you prefer), you start thinking of ways to get out. However, as with most things that are primarily physical your brain is not your friend. When you get your new habits sorted to the point that you no longer have to think about what you're doing, your speed will increase drastically.
But, in the meantime, for a few more weeks, you'll have to think about saving steps.
Keep your knife sharp, your station clean and your head down,
