My boss didn^t like the design of cream cot bed

I am sure that you will agree with me that being disappointed is one of the worst feelings in life. We don^t want to feel it too often as it is sad and might lead to a depression. On the other hand we should be prepared for the fact that we might come across it in our life. People who were never disappointed are probably people who have never tried anything. When you try new things and evolve you are more likely to be disappointed from time to time. That is because we all make mistakes and you can^t do nothing about it. Let me tell you when I have felt disappointed for the last time. I have decided that I will create a design of new cot bed and show it to my boss. He didn^t want me to do this it was not his order but I simply wanted to do something more. I thought that I have a great idea that I wanted to share with him. I have been working on this cot bed project for almost a month. Finally I have decided that it is time to present it. To my surprise my boss didn^t like this design of cot bed at all. He told me that they will never introduce it and that I shouldn^t have done it in the first place. Can you imagine how I felt when I have heard it? It was a disaster!
