Does acceptance of results mean having no expectations?

Karma yoga is action + attitude. Our attitude determines how we will respond to the situations. Acceptance of the results of our effort does NOT mean not having expectations- it just means to recognize and focus on efforts and clearly knowing that there are many factors beyond our control in the outcome. This attitude neutralizes our likes/dislikes and over time they have less influence on the choice less work we must do because of the several roles we assume for ourselves.
