As Tailscrape says, the training is a bit stressful at times, and it's easy to lose sight of the woods as you struggle through the trees - and that applies whether you're just starting your career or, ahem, a bit over halfway through it.. .Nevertheless, there are times when the vision becomes clear again, and you remember why you did this. For me (at least as far as my civil career goes), it was landing a 747 at JFK on a $hitty night about half-way through my line trainig, and feeling that I was beginning to get a grip of the aeroplane and the job (Self delusion? Probably!).. .It's difficult to say when that moment will arrive for you, but it will, sometime, somewhere.. .Stick with it!
