Time Blocking
Give every hour a job before the day starts.
Time blocking is the practice of assigning each portion of your day — usually in 30-minute to 2-hour chunks — to a specific activity in advance. Instead of working from a to-do list and reacting to whatever interrupts you, you decide ahead of time what you'll do and when. Cal Newport, Bill Gates, and Elon Musk are among its most public practitioners.
Three flavors of time blocking
Task blocking pairs specific items from your to-do list with calendar slots. Day theming dedicates each weekday to a category of work (Mondays for writing, Tuesdays for meetings, etc.). Time boxing sets a hard time limit on a task to prevent it from sprawling. Most people combine all three.
How to start
Open tomorrow's calendar tonight. Drop in your top three priorities as 60- to 90-minute deep-work blocks before any meetings. Batch shallow work — email, Slack, small admin — into one or two named blocks instead of letting it leak across the day. Leave 30% of the day unscheduled as buffer for the unexpected.
When the plan breaks
It will. The point isn't to follow the plan rigidly — it's to make conscious tradeoffs when reality intervenes. When an urgent request lands, move the block, don't abandon the framework. A re-planned day is still a planned day.
