Closed Doors-about ENTHUSIASM

I read at the door of a German post-office: “Note the opening times (9-12 a.m., 3-5 p.m.)!
To shake and shake again the door is useless!”
Originally: “Dienstzeiten beachten! Rütteln und schütteln ist zwecklos!”

more about ENTHUSIASM: Henry David Thoreau:
“The artist must work with serenity. A lot of enthusiasm spoils the work.”
