The cop who seeks to better himself may have a hard time finding an ideal mentor. Success entails valuing what we do and who we do it for. Unfortunately, some cops acquire an Us vs. Them mentality. "Them" can be everyone from suspects, to admin, to peers, to the citizens we serve. In a profession that offers ample opportunity for frustration, the temptation to put up walls and just say the hell with it can be strong.
