Goal Setting & Priorities
Time management tells you how to spend your hours. This is what decides which hours are worth spending at all.
Why It Matters
Skip this step and even a perfectly organized calendar just executes the wrong things efficiently. This is the Plan half of the cycle — decide what you're actually aiming for, and which few things matter most, before you start protecting time for any of it. Do it well and Time Management has something worth defending; skip it and the best productivity system in the world just helps you do more of whatever showed up first.
