For me it's finding and connecting musically with the right people. I think I depend on being creative in the moment(which fails sometimes) with someone, and not having some kind of premade content or idea.
I think there's a level that some musicians can reach where your mind is free and you tap into a source of infinite creativity. Is there a name for this? I've not heard too many teachings on this subject.
Thanks for all the feedback. I think the magic really happens when your relaxed, focused and aware but sometimes it's hard to breakthrough that state of mind.
