Toxic people defy logic. Some are blissfully unaware of the negative impact that they have on those around them, and others seem to derive satisfaction from creating chaos and pushing other people's buttons.

Confident people tend to challenge themselves and compete, even when their efforts yield small victories. Small victories build new androgen receptors in the areas of the brain responsible for reward and motivation.

People with a growth mindset believe that they can improve with effort. They outperform those with a fixed mindset, even when they have a lower IQ, because they embrace challenges, treating them as opportunities to learn something new.

Those of us in law enforcement must redouble our efforts to resist bias and prejudice. We must better understand the people we serve and protect - by trying to know, deep in our gut, what it feels like to be a law-abiding young black man walking on the street and encountering law enforcement. We must understand how that young man may see us.

Even though we don't always realize it, as the day goes on, we have increased difficulty exerting self-control and focusing on our work. As self-control wears out, we feel tired and find tasks to be more difficult, and our mood sours.
