Follow-through is one of the clearest forms of respect.

Saying you respect someone costs nothing and is easily doubted. Doing what you told them you would do is the version that cannot be faked, because it required you to arrange your time around their interests. People read follow-through as a statement about how much they matter, and they are usually right to.

Think of who you have quietly let down with small unkept things. Pick one and complete it this week, without explanation. The message it sends is larger than the task.
