Oftentimes we are focused on what we want (or think we deserve) to get: the promotion, recognition, award, reward, etc. When this is our focus, it is almost guaranteed that there is one thing we will get: frustrated!
On the other hand, when we focus on what we can give: our time, energy, attention, great performance, love, etc. we typically feel engaged, energized, focused, satisfied, and fulfilled. The irony, of course, is that we get much more when we are focused on giving.
