What is the alternative? Smile when others do well. Be happy and thrilled that others are reaching their goals and hitting new heights. We are one people and it serves us so much better if we are genuinely pleased to see another do well. Share the love!
It is a really good question......ask yourself and be true. If the answer is not 100 that it brightens your day to see others win, perhaps you are on a path of disservice. This applies on the dance floor, at the race, at the game, during the family dinner and on a date......smile when they thrive, it's good, it's authentic and it's liberating.
