#16-1. It's so hard when I have to, and so easy when I want to.
#16-2. Swallow your pride occasionally, it's non-fattening!

The first and third are related. It is possible to psyche ourselves up to do something with gusto, and that makes a difference to the results. Try it and you will see. Ultimately it can actually become a habit and you will be a valued member in every professional or social group.
