Tri Sigma`s annual character essay contest is now open! 💜
Each year, Tri Sigma participates in CHARACTER COUNTS! Week by hosting an essay contest encouraging collegiate sorority women to reflect on the importance of character.
This year`s theme focuses on a quote from The Secret Life of Bees. Author Sue Monk Kidd wrote, “The hardest thing on earth is choosing what matters.”
In 600 words or less, entrants should describe what matters to them and how it is connected to their character.
Winning entries will be awarded $300 for 1st place, $200 for 2nd place, and $100 for 3rd place. This contest is open to collegiate members of any national sorority. Visit the link in our bio to learn more or submit an essay!
