Improve your productivity by tracking your time and measuring your E-factor

This post details the author's personal journey and strategies for improving productivity by increasing 'deep work' and 'E-factor' (uninterrupted hours / body-present hours). It introduces concepts from 'Deep Work' and 'Peopleware', and describes personal workflow adjustments (email timing, self-improvement activities, routine) and environmental factors (separate room, routine, timezone, Slack/email policy, task journaling, asynchronous work) that enabled these improvements. The author shares a Google Spreadsheet template for time tracking and a GitLab project for task journaling as tools to support these practices.
