You make cameos in a dozen lives every day. The cashier, the bus driver, the new kid. Show up well.

Most of your effect on the world happens in interactions lasting under a minute. You move in and out of a dozen people’s days, barely registering it, and each of those moments lands somewhere for them. You cannot control what anyone is carrying. You can control whether your thirty seconds made the next hour slightly lighter or slightly worse.

Pick three of those tomorrow and be genuinely present in them. Look up, use their name if you know it, say the thank you like you mean it. Small effort, wide reach.
