CPL(H) and private flying
Heh - I hold a CPL, and an FI rating to boot.
As you probably guessed, I'm not flying professionally - my day job just got a lot more rewarding, and now I only fly for fun, which isn't a bad way to be.
I enjoyed the CPL - the extra theory stretched me, and the instruction wasn't wasted either.
The FI stretched me even further - to the limit of my flying skills, and I haven't had the opportunity to do anything beyond trial lessons with actual students. Although they and I very much enjoyed doing this, I can't see myself maintaining the FI, particularly in the current economic climate.
There are plenty of excellent schools who will eagerly take your money and train you to a higher level, and you'll find your flying more rewarding as a result.
Hope this helps!
