Chapter 34: An interesting session sparks a train of thought...is self-discipline an inbulit characteristic or is developed as part of training?

The aspect of self-discipline has always interested me. Is it something that is already a part of you, like a personality trait-some people may have the capacity to develop self-discipline more readily or is it something that can be developed through training, either mentally or physically?
This train of thought started after a recent Aikido session. The instructor handed the class over to one of the brown belt coaches. I always enjoy these sessions, not that I'm saying being taught all the time by the same person is boring- its just nice to experience a different train of thought about the aspects of Aikido.
The coach started by explaining a recent observation that she had seen at competitions and gradings-as a club we had become too 'soft', there was no purpose to our technique which was inhibiting our progress in our Aikido.
So we started by beginning with Tandaqondo (the hand and foot exercises) and then were asked to practice it again with a partner-just to see how our technique changed. I have to admit it was very strange-I was 'striking' a real person! In a way, it made it easier to do, but the theory is that the exercises should be practised as if you are striking someone anyway. That done- we were asked to practice the Kata techniques of 1-17 and regardless of being Uke or Tori, we had to come back into posture after every completing technique. I will be very honest here- none of us did it after every technique, quite frightening how sloppy things can become if you let them slip.
After this we were asked to pair up with a different partner and do a different Kata if we wanted but this time maintain eye contact and posture at all times. We were also asked to count each time our partner lost eye contact with us. Apparently, I lost eye contact about twice in total. Not bad really- but I suppose you could argue you should NEVER lose eye contact, but I think that is a matter of opinion really-in a club were there is limited mat space you need to keep one eye on your partner and one eye out for flying bodies in your direction!
At the end we were asked how we thought it had effected our aikido. A blue belt observed that it give us more self-discipline. Interesting point-Shouldn't a martial art encourage you to practice self-discipline on and off the mat whilst you are in the dojo? The Coach had one closing remark- if you practised coming back into posture and maintained eye contact in everything you did with Aikido, gradings would be a breeze.
Once I got home- I began to ponder, what is self-discipline? As well as being an Aikidocca, I'm also an Irish dancer. I have danced since I was about nine years old, so have been dancing quite a while. Irish Dance requires a fair bit of self-discipline- we start in a set starting position, and finish in a set finishing position, and bow to the audience. We are also not allowed to talk to one another on the floor as this encourages us to talk when we are during a performance-which is not professional, therefore it is discouraged in class.
When I first moved into the Senior group of the dance school, we had a bar installed in the classroom. We then shown exercises to do which would help to improve our flexibility and encouraged to use it before each class. The strange thing was out of a class of maybe 12 girls, only 2 or 3 (myself included) would use it. The point is- was that an exercise of developing self-discipline in us as dancers?
As a martial artist you realise that it requires a lot of self-discipline to develop further in a martial art. But the point is what exactly is self-discipline? Is it a frame of mind you develop through training to develop further or is it more a form of self-determination and will to suceed? I like to think that self-discipline is something that you develop as a part and parcel of training be it in dance, martial arts or music. It seems to be a way in which you can conduct yourself to self-improvement, but at the same time know yourself, when to push that little bit further but also know your own limitiations, and I think Aikido is a great way of exploring your inner self-its almost looking in a mirror really.
