19 inch data cabinets came back to us

I hate it when I invest my money and time into some project and it is a failure in the end. It means that I have lost a lot of time and I didn^t achieve anything. I don^t know if you agree with me but I believe it to be one of the worst feelings ever. Have you ever felt it? It is way better to take part in a business that turned out to be successful. That is obvious. What is even more frustrating is the fact that some people are able to affect your plan. Let me show you what I mean. Some time ago I have been working on introducing new 19 inch data cabinets to the market. I have been working on this project with few people and we were all really excited about it. When we have sent our first 19 inch data cabinets to the stores we were expecting to hear only positive tings about them. Unfortunately after few weeks we have received almost all of them back. We were really upset about it. It turned out to be a project with no future whatsoever. I am still not sure what went wrong with those 19 inch data cabinets. We must have forgotten about something important and thus the low quality of our products. Maybe it is the fault of one of my partners. I will try to establish it.
