We rarely see smiling faces in the business world these days. It seems seriousness is in trend and considered more professional. Ebullient & humorous behavior is deemed as taboo.
I feel seriousness reinforces arrogance & therefore cannot be a virtue. It weakens the spirit & makes you exhausted. Whereas humor strengthens humility, lifts the spirit & invigorates you. So don’t be Serious, celebrate life and don’t let this world adulterate your fortitude.
