Having low self-esteem and a shield of lard are not guarantees of safety. Having a warrior spirit, high self worth (most people are assaulted by someone they know, so if you think you're only worthy of hanging out with controlling low-life's, that's who you'll attract into your circle) and the ability to run, hit, kick and holler loudly are far more effective weapons against victimization.
