I'm no expert, but I say go for it. There are so many uses one can make of lucid dreams and if not all of them, then probably most of them are a step in the right direction of becoming better: having more confidence, feeling that you are in control of your life, feeling that you are on a way of understanding yourself more and more. These are all things that can be achieved and that can and will have a positive effect afterwards in your waking life.
