Whenever I clean my room, I feel weird. Clean feels static and uneventful, too good or too perfect. Something always has to be out of place for me to feel at ease. It's similar to how we play I think. If you play exactly what's on the page, it's actually wrong. There have to be differences, things played "uneven" to make phrases and make the music interesting. Now, of course it has to be clean, but in it's own way, and each of us have a different interpretation of that. I play very precise things differently than other people, because my personality and way of organizing music is different than theirs. It doesn't mean that either of us is wrong, as long as we can accomplish the character of the piece accurately.
My practice habits are very irregular and very spontaneous, but that's how I function. Other people have set times and plans written out and that works for them. My practice "journal" is comprised of quotes and that inspires my work that I do. Other people have specific goals for each day or big goals for several days. One uses a computer, another uses a small journal, someone uses black ink for technical issues and red for musical issues, etc. No one is wrong, but no one is right either. The same is true for how we play music. Some people don't like the way Hilary Hahn plays Bach, but I actually love it. Others love Joshua Bell's Bach, but I don't. It's all a matter of taste and preference. Find what works for you as a person and a musician, learn from others' experiences and ideas and see what works for you. As long as you get to the goal and can accomplish it, your process is fine. We can all learn a thing or two from each other, regardless if we have figured out a workable system, so always keep an open mind.
