Being a "passivist" may be fine in certain aspects of life but not in athletics. I have never found myself or another coach instruct an athlete to "be more passive". In fact, the opposite is the case. Cheerleaders even have cheers which encourage athletes to "B-E A-G-G-R-E-S-S-I-V-E". However, aggression isn't the answer either (as aggression involves the intent to harm someone). And that is why most athletes struggle with giving the correct amount of intensity in their sport and erring on being too passive. The athlete doesn't know what is being asked of them, nor do they know what to do to remedy the problem. We don't need to be angry/mad/upset or "fired up" to be intense. We merely need to understand that passivity doesn't have a place in most sports. Calm does but not passivity. Being "assertive" is what we must do. Being assertive refers to being intentional and intense at the right moments.
