How important is self-sacrifice to you? How often do you do it and to what extent? Are you constantly thinking of others before yourself? Do you do things only if you will benefit from it? There are many aspects of self-discipline in the martial arts, and I would like to know how important you believe this aspect to be. By "self-sacrifice", I mean giving of your time, effort, money, ect., to other people/putting others first, even when it means putting aside your own interests/preferences.
