I hope you have someone (or multiple someones) who brings you joy simply by being in his or her presence. Maybe you could make both your days by telling the lovely person so.
My husband is playing in the pit band for a local musical production. The musical director called after the first weekend of performances to tell my husband how much he appreciated his playing, attitude, and openness to learning. It made my husband's day.
We don't truly need appreciation to survive, but it sure helps us to thrive. Expressions of gratitude are always lovely and welcome.
