Cmon its great, you get to pay 15-17K for the privilege of having a bunch of muppet light twin drivers who look at you blankly when you say 'critical engine' tell you you're not a proper pilot
Jokes aside its worth doing as the difference in your flying and approach as a professional is night and day. Just make sure that once you finish your rating, you dont just sit on your hands. Keep reading, keep learning, listen to the more experienced guys and always deliver your best to your students. You may be 'over it' in 2 years from now, but from the perspective of your student, he/she is going through this for the first time, and is paying you a lot more than 15-17K for the privilege.
