I would ask you, do you want to learn to fly? Or do you want to get an NPPL?
If you want to learn to fly, then forget the licence as it will arrive when you are ready and have earned it.
If you just want an NPPL so you can go for a flight now and again then I suggest you lack the motivation in really wanting to learn to fly.
Enjoy your training for what it is, learning the skills you will require to be a safe pilot. Dont let one mishap put you off.
