Why not just start off with a few trips to take you out of your comfort zone of the PPL course and go somewhere new? Maybe a night stop somewhere you might not normally get to (better still, take your significant other with you for the trip and talk about what it's like).
Not all good flying needs to be taught, much of it can be learned on your own. That is part of what is meant by the old chestnut about a PPL being a licence to learn.
