Self discipline means deliberately aligning our energy with our values and priorities. Through mental practice we focus in on a task before us and lets other temptations and distractions pass us by.
Self-discipline asks that we endure frustration, disappointment, and pain in the service of a higher goal. It means being willing to push ourselves to the limits of our will and endurance if that is what is needed for success.
Self-discipline need not be harsh; it can take the form of a quiet resolve or determination that then directs our choices. It is exacting, but is rarely served by our being self-critical or self-denigrating. Self-discipline allows us to make use of whatever power and capabilities have been given us, to be all that we can in the service of our dreams.
