@annyuke: Thanks a lot! You already made the first and most important step by becoming a premium member. Now just keep doing the challenges every month, and you will inevitably get there. 98% of what you hear in my recording is the result of me doing the challenge month after month for almost six years now, and literally challenging myself by picking a piece at the upper end (or slightly beyond) my current playing abilities, even though sometimes it seemed completely impossible at the beginning of the month to get that down within just one month. Somehow it has always worked out. And remember: if you don’t make mistakes, you don’t practice. By definition, practicing means learning something you can’t play yet, so mistakes are inevitable and proof that you’re actually practicing. My personal experience is also, if I had the feeling I was just not getting better at a specific part no matter how much I practice, I would let it rest for a couple of days and work on something different, and when coming back later to that part, more often than not it would go much better right away. I don’t know if there’s scientifc research behind this phenomenon, but it’s definitely something I noticed for myself.
