Why Do I Love Playing?

Why do I love playing the violin? Today, someone asked me this question and I just realized the answer. After a long day of stress, even when I am exhausted and don't want to practice, I open the case and just feel excitement and joy. As soon as I start playing, all my troubles and headaches fall away and there is nothing but the music, the skill, the challenge. The world disappears and I lose myself. Words can't describe the love, peace, pure joy....
