Task List with Subtasks Template
Big tasks hide their progress. Launch the pricing page is one row until you break it into copy, layout, review, and publish \u2014 and then a list can tell you it is half done instead of not done. This sheet has a Level column: mark a row Task and it goes bold; mark the rows under it Subtask and they indent visually and count toward progress. The percent at the bottom counts subtasks, so a task is only finished when its pieces are.

Every outliner tempts you toward sub-sub-subtasks, and every list that goes there stops being read. Two levels — the thing, and the pieces of the thing — cover almost all real work and keep the sheet printable. If a subtask needs subtasks, it was a task; promote it and give it its own row.
Write subtasks as verbs that finish: send the draft, book the room. A subtask called Marketing never gets ticked because nothing ever completes it.
