One day, it was very hot and there was a big bear. He was very thirsty so he decided to go to a small lake in the forest to get a drink. 

When the bear arrived he was feeling hot, and before drinking the water, he started playing in the lake. He jumped and ran in it, and the water was getting out of the lake. 

However, the bear played in the lake for hours. In the end, there was not a single drop of water left in the lake, and the bear was unable to drink and had to find a new lake. 

The moral of the story: Before you rest, you must do all the things that are important to you, or you will take more time to do them.
