Zephyr - the "no expectations" concept is IMO, one of the toughest. It's really a discipline. Not just for your relationship with your ww, but in life.
Meditation helps me regain focus. But without getting too Buddhist on you, one of the main philosophies of it is that the cause of suffering is that we look for satisfaction in things that are impermanent. We attach happiness/hope, etc on events, people, things and even if we achieve it, it never is at the level we projected them to be on our mind and more often than not, we don't get them and end up being sad.
The more you can focus on enjoying the present moment and not let your mind wonder into the "whatif" futures or "hindsight" pasts - you'll be able to be pleasantly surprised with where you are - like the live music event you went to.
Easier said then done. I wish you the best of luck!
