Pushing One's Edge
In competitive games, it often pays off to exploit one's own strong suits against the opponent's weak suits.
For example, suppose you are playing table tennis and you know the player at the other side of the table has a weak left-hand play.
It is simply better to put the ball in their weak hand most of the game.
In this scenario, pushing your edge means putting the ball where you yourself have the stronger play.
More practically, in life, it's worth recognizing where your strengths are and where you can -- perhaps uniquely -- contribute.
It pays to double down on every advantage it may present and make decisions to press that advantage even further, so that it keeps compounding upon itself.
This works both ways: you should mold the situation so as to allow your strong skills to excel AND you should develop the skills needed to excel in a given situation.
