Being educated by books will only get you so far in a fight. If you don’t practice what you have learned, even a child can bring you to your knees. Just ask the man who was kicked in the groin by his tottler.
A while ago I wrote something on the topic of theoretical learning vs. practical learning and how important it is to actually practise.
It is important to remember that reading is great but does not bring you half as far as really learning something. You have to apply your knowledge to make it stick to your brain and to make good use of it in the first place. So don’t make the mistake of reading ten books about fitness before you go out for a run!
