 One of the key concepts of many schools of psychology is that human beings are most functional when every part of the mind has access to all other parts. In particular, this functionality is a matter of having full access to positive resources, such as memories of times when we were successful in our undertakings and the good feelings we associate with those accomplishments. Working from this level of functionality, then, when we take on a new task, for example, we first remember times in the past when we attempted something similar and accomplished our goals.
