Why can't I stop thinking when I meditate, am I doing it wrong?

You are not doing it wrong. Thinking during meditation is completely normal, because the mind produces thoughts the way the heart beats. The practice is not to stop thinking but to notice when you have been swept up in a thought and gently return your attention. That noticing and returning is the whole exercise, and every rep strengthens it. StillMind’s guided sessions give your attention a steady anchor, so getting lost and coming back feels natural rather than frustrating.
