Since then, two things happened. One is that I completely lost interest in meditation. The second is that I feel I've become a lot better at emotional regulation and self-awareness. It's hard to tell whether meditation actually played a role in this, or whether it was other things I was doing, or just a natural consequence of aging and accumulated experience.
Now my thoughts on meditation are that it's probably moderately beneficial, especially for someone like me prone to anxiety and depression and lacking in healthy lifestyle habits. But I'm skeptical of claims that it has unique benefits when compared to any other focused, rigorous activity like physical training, serious reading and writing, or playing a musical instrument. Or for that matter, eating a healthy diet and getting enough sleep.
