Its like learning any trade, and then trying to better yourself by starting your own business, there's nothing wrong with that.
What is wrong, is if you don't think you're getting value for money, i.e. coming out of a class or a course and thinking what have I learnt or achieved.
Now don't get me wrong here because I know that we have to do the hard physical sessions but courses are meant to develop our karate, we should be coming away from them saying to ourselves that was fantastic, I never knew that, I have actually learnt something IMO
