Might I add that if it is in your nature to look for guarantees in life, aviation is the lousiest of all choices.
If you love aviation, as most of us in this business do, then go for it, but don't go looking for guarantees.
The one absolute guarantee that I CAN give you is that if you do nothing about making your own future happen, nothing will happen at all.
