Since I imagine many of this forum's contributors have been PPL holders for quite some time I wonder if you recall what you did for your first flight after gaining the license.
After passing the GFT, I was two hours solo short for getting the license, so I spent those pottering about in the neighbourhood of the airfield and its practise areas.
My first flight after getting the license was spent on a short cross-country trip (without a passenger). My first flight with a passenger was a few weeks later -- he was a student pilot coming along on a trip to Bembridge because the plane didn't have a starter and I needed someone to be in the cockpit when I was out swinging the prop.
I'd recommend a cross-country hop to another field. You gain a sense of accomplishment along with consolidating your newly learned skills. It may look a little daunting, so pick a day with good weather!
