"He who plays advisor is no longer ambassador"

This quote by French playwright Pierre Corneille recommends that as soon as somebody takes on the function of an advisor, they can no longer be considered an ambassador. Simply put, when a person ends up being a consultant, they lose their capability to represent and speak on behalf of a larger group or company. This could be interpreted as a caution against getting too involved in the decision-making procedure, as it might compromise one's ability to remain objective and effectively fulfill the function of an ambassador. It likewise highlights the importance of keeping a clear distinction in between the functions of advisor and ambassador in order to prevent disputes of interest.
