I was motivated enough to stump up several Łks to pay for my MSc studies with the OU - but that doesn't mean it wasn't darn nice to get to go to an awards ceremony at the end of it, wear a gown, and be told I'm allowed to put MSc (CCI) (Open) after my name!
It's nice to get recognition from others of your accomplishment. Its also nice to be get something that you can use to show others your accomplishment (if you so wish). So some discrete wings (such as a lapel pin) that you can wear (if you want) would be great.
Epaulettes and rank insignia though should definately be for work only!
