This probably isn't much help but until someone else replies here goes.
When it came to choosing my trade at the careers office I only picked one (can you guess which one?). I didn't entertain the idea of other choices cause for me it was that or nothing. When you pick yours its worthwhile asking yourself if you would be happy doing any other job, or whether you simply want to get in no matter what? This could make an important difference as if you find yourself with a choice you didn't really have any interest in you may simply drop out when the going gets tough in training - cause whats the point for a job you don't want?, or else quit after your four years as you didn't get to fufill your dream to do whatever it is you wanted to do.
Please, pick very carefully for everyone's sake, not least of all yours. Its your life after all.
Oh, just to make clear so I'm not misrepresenting myself, I'm not in yet - done the selection centre and still waiting for the nursing board.
Good Luck,
