I agree with Quincy
Failure is an option - maybe not to you but circumstances can overcome your outlook.
What happens if you get ill, the fiance leaves (not saying it will happen!), you don't get trained - you only get trained in summer!!!!
you get a watch change, you get a unit change (not that you are by any means guaranteed that either)
etc etc etc
you get posted to Swanwick, tried the rents about here???
16k when you leave the college (IF you pass), won't get you that far.
REALITY IS A KILLER
