Learning Tae Kwon-Do techniques could help you with self-defence

when starting martial arts you may not be as fit as you would like but with time and your dedication in trying hard and not giving up you will get stronger in your body and mind

time away for you 

when you start to learning something new sometimes it take time to grasp the idea or concept of what going on, each person will do this in their own time, there is no rush or pressure, if you do not  get or understand what you are doing I would show again and again

help build a positive attitude about your self in your new skills that you are learning
