The is no "golden bullet" or "magic pill" when it comes to taking care of yourself. I don't even like the term "self defense" and more often than not I use the terms "self survival" or "self preservation", because I am not fan of play defense, but rather shifting to a strong and violent offense as soon as possible. Here is a video clip I wanted to share that deals with some common situations in which attacks & robberies frequently happen. Again, this is not to give you all the answers, but rather maybe some options you just haven't yet considered.
