Believe in people before they have proof. You might be the reason they get it.

Most people carry a harsh private estimate of themselves and quietly check it against what others seem to expect. Being treated as capable before you have proven anything does not just feel good, it changes what you are willing to attempt. That is a real thing you can hand someone, and it costs nothing except being early. Now and then you back the wrong person, which is survivable.

Think of somebody near you who is trying something quietly and tell them you think they will get there. Be specific about why. Ask about it again in a month, because the follow-up is what proves you meant it.
