Mindfulness meditation is an interesting and refreshing practice, but just like any "one weird trick" clickbait title (because wired can't help themselves) engaging in this practice alone and expecting a magical complete revival of your life is not only rediculous, but may sabotage any long term effort.
That said, I could see the average HN reader getting some useful skills out of doing nothing (literally) for a specific amount of time.
I don't meditate, but I've found it useful to take some mornings or afternoons and go for 5-10 mile walks. I usually take a small notebook and some pens to write down ideas. If I don't have the notebook, I can still take notes on my phone or scraps of paper.
I've never counted the distance exactly, but I would estimate that I've walked a couple of thousand miles around Berkeley and surrounding towns. It's especially nice in summer in East Bay in some of the quiet neighborhoods.
