Discuss why two people with similar abilities may have very different expectancies for performing at a high level.

Explanation:

The main and major reason why, is the obvious one. The first reason that comes to the mind.

The minds of the two individuals are not the same, and despite the fact that they have similar abilities, they might not necessarily get the job done on time because of other commitments either of them have. Even if they both have none, there's always a distinguishing factor, and that will always trump, thus making them have different expectancies for performing at a high level.
