Meditation and attention
The basic idea of meditation is simple. Every time your mind begins to shift its spotlight away from your breath and you get lost in thought, you simply bring your attention back to your breath. And then you repeat this again and again until your meditation timer sounds. The point is that every time you bring your attention back to your breath, you work out your “attention muscle”, if you want to call it that. Then, over time your focus, concentration, and attention span improve. Chris Baily
