I can't remember exactly who it was that said this, and I don't know if it helps you at all, but the thread title just made me think of this quote that I have held to heart ever since I heard it.
You spend countless hours and years, learning and mastering all the chords, scales and theories, just so you can throw it all out the window and just play what you feel from the heart.
maybe not exactly like that, but that's how I interpret it. You know what you feel, it may take a while to translate it, but just go with it.
