Well said. Since I approach this forum with the utmost candor in all my replies, I will even broach the prickly subject of organized religion sometimes if it's directly applicable.

In this case, I simply illustrate what works for me.
Anyway, back more specifically on topic, it's not normally my style to suggest something so elemental as being present, but that's a vital part of this formula, amongst other things. The thing I see with musicians far more often than I care to is a deeply ingrained sense of marginalized self-worth (which as we all know can have roots back to many other circumstances/incidents/traumas/suppression in one's life). I see it as a crippling disease, in that, from an objective standpoint, a player could be doing more than fine on a session technically, but then you see the fine art of self-sabotage at work.
Part of my "success" is that I do a fairly good job being comfortable in my own skin, comfortable around people, good at adapting, good at listening. I do not take that for granted one moment. Because I've seen many a player who can play circles around me, yet they scuttle their own chances right before your eyes during the course of a day in the studio. I've seen it too many times to gloss it over. And now that evidently I'm a full-blown record producer, I see it even more.
Very interesting stuff.
