Congrats on your promotion.
In my past live as an executive...my coach/mentor always sent me a note as I got promoted...here is mine to you.
The fundamental difference between moving to a new company and getting promoted from within is that you are already on track. Unlike when you join an organization for the first time and have to create ' a new positioning ' for yourself.
When you are promoted from within,people already know you or know people who know you. Thus this is, to a large degree, an exercise to ' repositioning ' yourself within Ananda.
