Decide what YOU want to do with your flying and set some goals, doing the PPL is a target and that is why many pack in after, they reach the goal and then do not know where to go from there, setting a new target gives focus, a good one for a new PPL is something like the UH Advanced PPL course, otherwise look at doing a basic aeros course with an aim at taking part in a basic competition aeros event/do the IMC or basic IR course/learn to fly a Taildragger/flying abroad to a destination well into Europe - another pilot to do this in tandem with is good here, whatever you do a target will help, and once you reach this target you will probably have more of an idea how you want to use your PPL.
