Seven time-management techniques that earn their place by having either measurable evidence or decades of consistent practitioner reports. Each works alone; they also stack.

1. Time-blocking

Pre-allocate blocks of the day to specific categories of work rather than to a task list. The mental overhead of deciding what to do next evaporates, which is where most of the leakage happens.

2. Pomodoro (25 / 5)

Twenty-five minutes of work, five minutes of break. The structure is more important than the specific intervals; any fixed-work-then-fixed-break rhythm produces the effect.

3. Eat the frog

Brian Tracy's framing: do the hardest thing first. Morning willpower is a limited resource; spending it on the worst task protects the rest of the day.

4. Two-minute rule

If a task takes under two minutes, do it now rather than logging it. Keeps micro-tasks from clogging the list.

5. Weekly review

Fifteen minutes, every Friday. What worked, what didn't, what's different next week. The single most correlated practice with sustained productivity improvement.

6. Say no in writing

Committing to decline in writing makes the decline stick. A verbal "maybe" becomes a yes; a written "I can't take this on" doesn't.

7. Single-task under pressure

When the calendar tightens, the reflex to have four tabs open is exactly wrong. Multitasking under pressure is a tax; close three things and finish the first faster.

Pick three. Running three well beats running seven poorly.
