Over-Pride
It is said that there was once a strong relationship between the Frogs and the Birds. One day, Frog told them that she wished to fly in the sky with the birds. They assured her they would do what they could to help her.
"So, as you two hold this stick on either side, I'll bite the middle of it, and we'll continue flying," she said. As soon as they agreed, they took off. After a few minutes, Frog looked down and felt very happy.
Very surprised to see a frog in the sky, other birds came flying and asked, "How did this happen? Who came up with the idea?" They directed their question to the two birds.
Frog, unable to resist her pride, interrupted the two birds and said, "It was me!" The moment she spoke, she lost her grip and fell to the ground.
Moral: Over-Pride leads to failure!
