Half-done is the most expensive kind of done. You pay for the effort and get none of the result.

An unfinished job has already consumed the effort and delivered none of the benefit, which makes it the worst place to stop. Half-built things also usually need partly undoing before they can be completed, so the cost grows while you wait. Starting many things and completing few feels productive and leaves you with nothing usable. Finishing is where the value appears.

Count the half-finished things you are carrying and pick one to complete this week. Abandon one of the others on purpose and properly. Then hold yourself to two live projects until one of them is actually done.
