A slow beginning can still be moving at the pace the task requires.

Early progress is usually invisible, because the first stretch of anything is spent learning the shape of it. Nothing is being produced yet, which is easy to mistake for nothing happening. Speed measured against someone else’s middle will always make your beginning look like failure.

Ask what this particular task actually requires rather than how fast you wish it were going. Set a marker a month out that would count as real progress at that honest pace, and judge yourself against that instead of against impatience.
