good luck, In looking at our list the only addition I can see to the problems of aviation that have been there for you from the begining is #7. In today's world that can indeed cause some problems but I don't think any of them are insurmountable.

Training failures are hard to take at first but I'm always more impressed by the guy who pulls himself back up then those who always just coasted along.

With a MBA and your flying experience you will be able overcome this, give it some time.
