For me, it's all about setting realistic goals and rewarding myself when I hit them. It's not about being superhuman, just about being better than I was yesterday. That mindset helps me stay motivated and focused.
I'm still experimenting, but I think I'm a no-music guy too. I like being able to focus on my breathing and pace, and music can be a distraction. But hey, if it works for you, that's all that matters!
