The ability to focus deeply, without distraction, on hard mental work is becoming rare — and rare skills are valuable.

• Deep work means focusing completely, with no distractions, on a mentally demanding task that pushes your abilities.
• Shallow, easy tasks (email, quick meetings) are easy to copy or automate; deep work is not.
• In today's world full of information, being able to quickly learn hard things is a huge advantage.
• People who can do deep work well are becoming more valuable, not less, as distractions everywhere increase.
