You sentence with 'confident', which is an adjective, makes no sense at all. What us the word 'keed' supposed to be?

Prize: I received the first prize in the racing competition, indicating an award or recognition.

2) Confidant: Maria is my most confidant friend that I can trust and share my concerns with.
Confident: Don't blindly have confidence in everyone until you assess and evaluate them.
