Attention is a Muscle

Focus is not a talent you either have or lack. It is a skill that strengthens with use and atrophies with neglect.

Studies of meditation and sustained attention have linked weeks of regular practice to measurable changes in brain areas tied to focus. Heavy multitasking seems to push the other way. Every hour spent jumping between tabs trains your brain to be worse at focus — practice the scatter, and you get better at scattering.
