I like to keep my practice well rounded, so the new things I'm learning have time to integrate in the deep brain. Think einstein working in a patent office. Often our most profound developments come when we least expect them, after we have spent time focussed on something else.
Obviously time spent on the fretboad is key. I like to find my way into the flowstate, where I'm not thinking so much as doing, then I start to find whatever I have been practicing will begin to manifest itself as musical ideas.
I go out and street perform fairly often. Getting real life feedback helps me discern what is musical/tasteful
