Also don't forget that no matter how great you get you will still shake like a leaf. Not every day and not every flight but when you fly that plane you have spent months on or the plane that you always wanted. I think the nervous part is what keeps bringing up back.
I think anyone that flies should fly on a sim (FMS, RF, whatever). You have to get those thumbs working without thinking and learn what you can and can't get away with.
CONGRATS! It's worse than crack! Your addicted~!
