Question
Why does time blocking fail?
Quick Answer
Blocking time but treating the blocks as soft suggestions rather than commitments. The most common pattern: you block 9 to 11 for deep work, an 'urgent' Slack message arrives at 9:15, and you tell yourself you'll return to the block after this one thing. You won't. The block is gone. Time blocking only works when you defend the blocks with the same seriousness you defend external meetings.
The fix: Open your calendar for next week. Identify the single most important piece of work you need to advance. Block a minimum of 90 uninterrupted minutes for it on at least two days. Label the block with the specific work, not a category — 'Write migration scripts for user table' rather than 'Deep work.' At the end of the week, compare what you accomplished in those blocks versus equivalent unblocked time.
The underlying principle is straightforward: Assigning specific blocks of time to specific types of work ensures important work gets done.
