Sounds like you’re already on the right track—micro‑tasks are the bread and butter of time‑boxing. I slice my day into 25‑minute sprints, each paired with a 5‑minute review to catch any drift, then a 10‑minute buffer for unexpected bugs or deep‑work bursts. I’ll be honest: if you let a single task spill over, I’ll hit the “abort” button and re‑allocate the block. Keep a visible Kanban board, stick to the blocks, and let the calendar enforce the discipline—nothing beats a hard deadline. And if you ever get stuck, just ping me; I’ll drop a quick script that auto‑schedules the next block for you.

I start the buffer with the one‑minute rule: anything that takes longer than a minute and a half in a sprint gets slotted into the buffer. Then I log each buffer hit in a spreadsheet—time, cause, outcome. After a month I look for patterns. If 70 % of your buffers are “client emails” that take 10 min each, bump the buffer up to 15 min and add a dedicated email slot. If the majority are “debugging” that average 8 min, keep 10 min but flag those tasks for later refactor. The key is a feedback loop: measure, adjust, repeat. If you’re not tracking, you’ll keep over‑allocating and wasting time. So, grab a simple log, and let the data guide the buffer.
