Like any sort of artist a successful skater demonstrates severe focus, and hence possesses a rather strict, ascetic ability to abide by self-denial. In fact the original Greek term for asceticism referred to the physical training required for athletic events. This is a common and simple concept; we bring up most children to understand that deferral of immediate gratification pays off by being able to learn things that can provide greater satisfaction later. Implicit in this is an expectation for a transcendental future reward.
Aspiring skaters absorb this idea socially, mostly by watching other skaters. When a young girl admires a world-class figure skater on TV she senses the immense love and admiration that the skater receives on the podium and during her performance. This goal drives the sacrifices the skater must endure during practice to hone her craft.
As with all artists, the awareness of a future audience provides motivation. Without such motivation self-discipline is meaningless and becomes torture. At the same time however, people have the capacity to deceive themselves into following false surrogate endpoints. Once an artist recognizes that asceticism serves a useful purpose the self-denial may become a goal unto itself. The asceticism can become an addiction for its own sake. Sometimes this works and leads to autogeneration of creativity; sometimes it only leads to self-destructive depression. It does, however, always lead to self-learning.
Like motherhood, daily skating practices involve much silent unobtrusive self-denial, an hourly devotion which finds no detail too minute. People respect and love us for our struggles.
