That post grading feeling

"One of the most amazing things about Aikido is the way it can take one scrawny person and change them into something that’s well, interesting, like they can take on the whole world, at least that’s how I felt after my first grading to white belt-a bit like walking on air out of the dojo."

talks about Aikido but the feeling is the same in any Martial Arts.

There is always a lot of other people telling you how good it is for you but to experience it yourself is the highest benefit I feel.
