Three months of strict time-blocking

An experiment with rigid daily scheduling. Mixed results.

In September I read Cal Newport's case for time-blocking and decided to commit. Every day for three months: every 15-minute block of working hours assigned to a specific task in advance. Here's what happened.

The setup

Each evening I'd block out the following day in a paper notebook. Tasks pulled from my todo list, slotted into time windows. Email had specific windows. Deep work had longer blocks. Breaks were scheduled.

What worked

Week 1-3 — Honeymoon

I got more done in three weeks than I had in two months prior. The scheduling forced me to confront which tasks actually mattered and which were performative busywork.

Week 4-6 — Settling in

The novelty wore off but the structure held. Deep work blocks consistently produced something. I was less anxious during off-hours because I knew tomorrow was planned.

What backfired

Week 7-9 — Cracks appear

Days that didn't go according to plan (most of them) created a sense of failure. I started feeling like the schedule was the work, not the actual work.

Week 10-12 — Diminishing returns

The overhead of scheduling started eating into the time I was supposedly gaining. I spent 30 minutes a night planning a day that often blew up by 10am.

What I kept

I dropped strict time-blocking. I kept the practice of choosing 2-3 "must-finish" tasks each day and protecting time for them. The 15-minute granularity was overkill for me, but the underlying idea — be intentional about your hours — survived.
