There's no reason that you need to "give up" flying altogether...why not fly for fun?!
One of the problems we have is an ever increasing number of controllers that have no flying experience...10hrs of "flight deck time" doesn't give a trainee controller an appreciation for what occurs on the flight deck. Having said that, just because you are a pilot doesn't guarantee you'll make it as a controller, but it sure gives you a great headstart!!
In the same vein, it would be good to see more pilots, particularly RPTs, coming up to the towers to see what it's like on the other side of the microphone...might give them a better appreciation of some of the challenges we face (although we still have some swine flu visitor restrictions).
