Every heart that has beat strongly and cheerfully has left a hopeful impulse behind it in the world, and bettered the tradition of mankind.

Courage and good cheer are contagious in a way that outlasts the person carrying them. Someone steady once made steadiness look possible to you, and you have been quietly borrowing it since. That is how it travels, not as advice but as evidence. What you do with your own ordinary days gets handed along the same way, mostly to people you will never hear about.

You cannot manufacture cheer, so do not try. Notice instead where you set the tone this week, at a table or in a message, and choose the slightly warmer version. Somebody is taking the reading.
