Effective coaches need to:

A) focus most on the coaching philosophy
B) focus on the personality of the people involved
C) manipulate coaching sessions to their advantage
D) tend to both human and business needs

Effective coaches need to balance both the human needs of their athletes or team members and the business needs of the sport or organization. This includes understanding and working with different personalities, but also developing a coaching philosophy that aligns with the goals and values of the team or organization. Manipulating coaching sessions for personal gain should not be a priority for a coach who wants to build a successful and ethical coaching career.
