People remember teachers who made competence feel possible.

What people remember from good teaching is rarely the content. It is the feeling that the thing was learnable and that they might be the sort of person who could learn it. That impression does more work over a lifetime than any particular lesson, because it determines what they are willing to attempt afterwards.

When you help someone, pay attention to whether they leave feeling more capable. Notice progress out loud. It costs nothing and it shapes what they try next year.
