Yes that's good. Using MMA for self-defense will take you quite a bit of time. If you are looking for very a very effective means of defending yourself a series of Krav Maga (http://en.wikipedia.org/wiki/Krav_Maga) classes can help. Nothing replaces sustained and constant training for some people that's not what they are going to do. In place of that you need something. For example even though I have a background (way way back) in certain things I fall back to some very simple methods that can be used by many if needed. Obviously the first is awareness, avoidance, etc. but defense and then disable are there to be called upon if needed.
