Frustration is normal Tom. I think the variance in how it gets to us comes down to how much pressure we put on ourselves. At my age I'm not too worried about how accurate or fast I can play. It's important that I continue playing and learning. Those are what's most important to me for this hobby.

However, you may be younger and more gifted and have higher expectations. If that is the case your level of pressure is going to be higher than mine.
