Even though I've done hundreds of hours, I still suck at meditation. The amount of progress I make on my to-do list during them is embarrassing.
But, not only is that OK, it's the point. Meditation isn't about perfection. It's a practice. Every time your mind wanders, you are learning how to bring it back. You learn how to recover. How to focus. How to let go.
So if your mind wanders 43 times in your short session. Great. 43 reps to build those recovery, focus, and letting go muscles.
So today, re-frame that struggle and embrace every stumble. That's the whole point.
