How to become the most wanted employee around

A book in the useful style of 50 short pieces (each only a few pages long) containing an idea to improve your life in employment.
Ok so some of the ideas are obvious but many of them make you think of how you approach your job.
The key message running throughout the book is that if you want to get on then you need to be different and stand out in some way (or ways).  Oh and do something you really enjoy!
