I am not the calmest guy in the world. And I have a lot of strength as I was very good football player in the high school. I chose education from sport and I do not regret it but sometimes my sportsmen soul is taking control over my reason. I am a big fan of new technologies and I created a small server room in the basement of my house. It is nothing special but I spend there all my free time and I try to make it as useful as possible. I have four big server rack there and a lot of small computers and monitors. I bought many of those devices on the internet from people that were selling them on online auctions. Thanks to that I saved a lot of money and I can think now about buying some more stuff. As I said sometimes I use strength before I try to use my mind. Some time ago I was mounting new devices and I had to remove a rack shelf from the server rack. Unfortunately it sucked and I could not move it. I tried to pull it but it was jammed. It looked like some curves were blocking the rack shelf. So instead of using screwdriver I used my physical strength. Well the effect was that I managed to pull out the rack shelf but I broke some elements of server rack. Now there is no option that I can use this place to mount additional devices there. It is broken for good. And all because I did not think but I used my strength instead of that.
