Bob, unfortunately, I don't have much words of wisdom to add here. I am just posting in to say that I feel I am in a similar situation. I look back to a certain point in my life, and I think that I had a clearer idea in mind then of what I was doing and wanting. That my chops were crisper, my memory better, my passion stronger, and my courage greater.
How do we get there again ? I don't think we do. The truth is, it wasn't good enough for me then either, and it would not be good enough for me now. Life has changed for me since then, I need and want an entirely new edge. And an entirely better one. Maybe it is similar for you ?
How do we get there then ? I just feel like I really don't know. But lately, I have been thinking that the things I want do not lay exactly within
what I play, nor in
where I play,
whom I play for, exactly
how I practice, how much I perform, and not even truly in my teachers (not that they do not hold a very important place in the matter for which I am extremely grateful), not in schools and so on... but, you know, somewhere or something else, or all of them together, or something mystical that I can't seem to define at this point in my life

(maybe our edges have something to do simply with who we already are and are willing to let ouselves be... ). All as Sir Bernhard indicated in a quote within a post awhile back.
How do we find it and bring it out ? That's what I am wondering in my life right now.
