I always considered meditation a kind-of inward focus. Like, you're not ridding yourself of thoughts. You're deliberately ignoring outside stimulus. That's why people meditating will typically close their eyes, relax their body, play some kind of white noise to deaden outside sounds, burn some incense to occlude any distracting scents, etc. Also why some kind of physical practice like long distance running or yoga is helpful - you're leveraging exhaustion to encourage relaxation.

For someone with ADHD, that probably does feel like a superpower. But it's more like a muscle that you develop over time. Little kids are notoriously bad at it. Much older people tend to fall into a meditative state more easily.
