EXCELLENCE IS AN EXPLICIT UNDERSTANDING OF THE EFFORT REQUIRED TO GIVE OF ONE’S BEST – IT IS ACCEPTANCE OF HIGH    EXPECTATIONS IN ORDER TO ACHIEVE A PERSONAL BEST – EGO!
Striving for excellence is an intentional and purposeful focus to give of one’s best, which is often an internalised desire to be respected.  It means the learner can be directed using  intrinsic motivation (ego: need)  as well as extrinsic rewards (desires: want) – the rewards of doing something well need time to develop as they are abstract and this logic is a late developer.
In younger years, many learners see completion as quantity: a page of writing, a set of questions, etc.  The educator needs to guide students toward believing in their personal best (PB).  This creates competition not with others but with oneself by stroking the ego.
Striving for excellence is being having high expectations, measuring attainment against goals, being held accountable.
