Because skills are the vocabulary for expressing oneself.

And why should I try my hardest, put my whole heart on the line, push myself to my limit, and risk the agony of losing an absolute heartbreaker?

Because.

We need to put ourselves out there, give it our all, and reap the lesson, win or lose. The fact of the matter is that there will be nothing learned from any challenge in which we don’t try our hardest. Growth comes at the point of resistance. We learn by pushing ourselves and finding what really lies at the outer reaches of our abilities.
