Why time yourself
Measurement changes behavior. When you time an activity, you build an accurate sense of how long things actually take, not how long they feel. This is useful for improving estimates, identifying time sinks, and building awareness of where your time goes.
Athletes, students, and professionals all use stopwatches for different reasons, but the underlying principle is the same: what gets measured gets managed. Start timing the things that matter to you.
