I think you should make peace with yourself. At the time, it was the right thing to do (even if you think the complete opposite now), and you did it. Learn from it, consider everything as an experience, and keep doing what you love. 23 is nothing, you have plenty of time ahead and many people start their lifelong hobbies/passions at a later age anyway. Nothing is wasted. You enjoyed your time playing WoW, and now you want to try other hobbies, go on and try them! Whatever you do, don't consider anything in the past as "wasted".
