I miss some days but try to play every day. I dont look upon it as practice. As a kid when I practiced for my lessons I only put in a half hour every day and it was pretty much a chore. NOw its just for pleasure, it relieves the stress. I play in the kitchen or bathroom where the sound is better. I believe any playing even just plain noodling is a finger exercise and will make its way into the brain or muscle memory. I do notice that If I dont play for a few days my playing is somewhat better or fresher if you will. So a break is not always a bad Idea. Cheers Petr
