Im 19 years old and have never done any martial arts before. I love taekwondo, am I too old considering that Ive never done any martial arts before, isnt martial arts something you have to start with when youre a kid, like swimming. I dont want to just learn it, I want to become the best xD is it too late for that if I start at this age? I know that most people start when theyre like 10 years old. Or even 5, is 19 too late?
