What Color Is Your Parachute is excellent. You might check using the DISC model for a starting point. Provides an in depth analysis of your communication styles and what motivates you.
I have been a DR customer for years (High Beams and Fat Beams). Have recently switched to D'addario EPS Pro Steels (EPS 165-5). Fender Am Deluxe Jazz 5, Xotic XJ-1T, Lakland 55-02 sound better and last longer.
