Discover why building concentration requires more than just scheduling time; it demands active training and weaning the mind from its dependence on distraction. Clifford Nass's research shows that constant switching creates "mental wrecks" who cannot focus even when they intend to. We propose four strategies to rewire your brain:

1. Schedule Breaks from Focus: Instead of taking occasional breaks from distraction (like an Internet Sabbath), schedule blocks for Internet use and strictly avoid connectivity outside those times. This turns avoidance into a structured "session of concentration calisthenics".

2. Work Like Teddy Roosevelt: Practice interval training for your attention by identifying a deep task and setting a hard deadline that drastically reduces the time normally allotted. This forces you to achieve higher levels of intensity.

3. Meditate Productively: Leverage periods when you are physically occupied but mentally free (walking, showering) to focus intently on a single professional problem. This practice strengthens distraction-resisting muscles and concentration ability.

4. Memorize a Deck of Cards: Learn memory techniques (like Ron White's method) to systematically train and improve your attentional control, a skill that translates directly to better deep work ability.
