The best help makes itself less necessary over time.

The measure of good help is that it works itself out of a job. The person learns the thing, gains the footing, and stops needing you for that. Help that permanently installs you as necessary is serving somebody, and it may not be the person receiving it.

Check in on anyone you have been helping for a long while. Ask whether the arrangement is still building anything. If it has become a groove that neither of you chose, it is worth changing gently rather than continuing out of habit.
