Some people say that it is easier to follow your commitments when you share it with the public. For example when you declare that you will stop smoking and tell it to the others who will be able to control your declaration, you have more chances of succeeding. In my opinion that is the reason why so many people have different blogs or other accounts on social services online. When they share their ideas, dreams with each other they are somehow obliged to follow them. Otherwise they might be widely criticized. They won´t be able to deny what they have said as everything stays on the internet forever. To prove you that I am right I will show you an example that resembles this theory. There is a guy who wanted to lose some weight. He was advised to use supplements in order to do it more efficiently. He decided to run a video blog where he will be showing the effects of using those supplements as well as working out. Thanks to this he will be checked on by a lot of people from the internet. He wouldn´t be able to deny that he was or wasn´t trying to lose his weight. He could be laughed at by people and you know that everyone would like to avoid it. Do you understand now?
