In the last several decades there has been a revolution going on in the self-development area. Every day it becomes more and more clear that one of the main things influencing the quality of people's lives is their way of thinking. One's mental attitude influences not only their mental aspects like self-esteem and confidence but it outspreads to literally all areas of life including health, relationships or financial situation. Among other various tools, one of the widely spread techniques for enhancing one's life is using affirmations or autosuggestions. This paper exhibits the origins and various uses of affirmations in several life areas and tries to give a simple scientific explanation about how and why affirmations work. It then shows how this process can be alleviated and accelerated with the help of personal computers. A computer application developed by the author that serves this purpose is also described.
