I’m a CEO. Pressure and stress come with my job. That’s not always a bad thing, as Justin Menkes notes in his book, “Better Under Pressure.” Some pressure is good. But a couple of years ago, the demands of being in charge took a serious toll on me. I’d read that CEOs including hip hop mogul Russell Simmons and Ford’s Bill Ford both meditate, so I asked my executive coach for his opinion. Most of his clientele are professional athletes, and turns out that for them he often recommends an iPad app called Inner Balance by HeartMath. He suggested that I try it.
