Chris, that sounds like a very sensible idea. Go away and find out if you actually like flying. The chances are that you'll be bowled over by it. I don't think there's a feeling in the world like being at the controls of an aircraft.
And even if you decide not to take up flying as a career, I don't think the money spent on a PPL would be wasted. A PPL will always look good on a CV/resume, no matter what job you are going for. It proves good technical ability, an ability to master some fairly non-intuitive concepts and a good deal of staying power.
So go enjoy your PPL course, I certainly wish I could bugger off and play in a single a bit more. And the best of luck.
