Give one important thing more time than ten unimportant things receive together.

Ten small things share the day and each gets a fragment, which is usually enough to complete them and never enough to do anything remarkable. One important thing given the same total time can go somewhere none of them could. The arithmetic is identical and the outcome is not.

Try giving a single significant task a block larger than everything else combined, even once this week. Let the small things wait or go undone. Notice what becomes possible when something receives disproportionate time.
