Serious answer - what Foxmoth said, above. Especially the aeros bit with a really good instructor, even if you don't want to do aeros long term. It will teach you better than any other form of flying how to fly any aeroplane correctly.
The PPL syllabus of necessity includes many half-truths, especially regarding how aeroplanes fly and why they sometimes don't. Aeros blows all that away and leaves you with full knowledge and confidence in handling the aeroplane by feel and thought and judgement rather than rote, right up to and beyond the edge. It is a great foundation on which to build any form of future flying hobby.
