Practice makes................well, not perfect, no one ever gets perfect. But you can definitely expect skill level plateaus. You may stay at the same level for years before making the next break through. And break throughs don't always come when you are working the hardest either. You might take a break or go on vacation, or see something on TV and it might change your attitude or perspective that tiny little bit that makes the difference.
