The stock price is a reflection of expectations. 

Exceed expectations, and the price shoots up.

Fail to meet expectations, and the price plummets. 

How we are perceived - with the work we do, in the relationships we have - follows the same principle.

Like most companies try to do at their quarterly earnings, we need to be setting up expectations that will be received well, and we need to be exceeding those expectations consistently. 

Or, at the very least, be meeting them.
