When you have a rack shelf you can install everything well
When you come up with some idea, you have to be sure that you are prepared to make this idea real, it seems to obvious when you want to achieve something seriously. Otherwise you can still dream about this idea, but without particular preparations it will be still only an idea that is impossible to be realized. Such situation can be observed in many different moments and it is nothing surprising because there are many situations in our lives that won^t means success for us unless we do everything well. Some time ago I met a friend who has started own business and he had to invest particular sums of money in many different things. He told me that it was really important to run own server and he had to buy special electronic equipment. But before he bought any electronic equipment, he had to buy a rack shelf to his server room, because otherwise there was no option for installing all of the equipment. In case of my friend it was really important to do some basic preparations because without this rack shelf it would be really impossible to run own server as there wouldn^t be proper place to install all of the electronic equipment and what can be observed we can experience many similar situations no matter what they actually concern.
