Information technology in our life. In an our electronic informational age we interact with different types of information more and more. Among these types we have two big groups, first group is useful information and second group is worthless. First group include science data, information related to our work, information which provide some instructions, information which can hep planing our life and our time, and other types which could be helpful for us. Helpful means information makes us better, lets us reach our goals. Second group include most part of information from social networks like Instagram, Facebook, Twitter etc. Information from the second group doesn’t bring any help for us. It’s only for a laugh, because in most cases people got this information, say «ha-ha» and go next. It’s useless information. Yes, sometime we need in this type of information but not in most part of our time. Information is like a fire, if you can manage in it’s great, if not - expect for a troubles. So, why people use information technology doesn't seems happy? Let's see on social networks, to Instagram for exapmle. What you see? Happiness. Why? Because people want to share their happiness, their carefree life. But not many people share their unhappiness. Have you seen photos with people’s troubles, which would say «Hey, see I have a big problems»? I don’t think so. When we look to other people’s happy photos we get negative, because we think that our life is worse, but it’s not true and these thoughts makes us unhappy. Fortunately, we can limit ourselves in Instagram using :) Ok, social network not evil at all. It very useful if you need to connect with your friend or colleagues in other countries. It’s a glorious tool for advertising your business. You should use it right. I think technology doesn’t guilty that some people don’t know how to use it.
