easy answer. Go places. Put as many different airfields in that logbook, for your experience more than anything. Network. And I mean go visit flying schools. Say hello. Tell people you're just hour building and seeing how many places you can visit, really getting out and about instead of circuit bashing. If you're planning on instructing, meet the companies where you might just be chasing a job one day. If they can put a face to a name, more chance of a look in later, obviously flying in to places in a professional manner might just help too, LOL.
Enjoy it. It's supposed to be enjoyable, but make sure you practice being accurate as possible. Nail the heights/speeds/configurations you want. Give yourself set targets to fly at, ie climb to x' then descend to y' get those timed turns perfect at rate one with climbs thrown in. 360 degrees rate one and climb 1000'. Then descend doing same. The more you're capable of doing before the CPL course, the easier it'll be. Do an IMC rating perhaps during the hour building. Night rating would be useful too with the darker nights coming up.
Have a nice time whatever you do.
