People have a desire to achieve self-fulfillment. Sometimes, although they want to achieve it, they cannot do so because of their current circumstances. They may feel separation and frustration. In an ideal environment, people try to attain what they want. That is human instinct. However, they are stuck between fear and freedom. Past memories can be a fundamental basis for future self-fulfillment, and it seems that memories are closely connected with each other. In short, self-fulfillment and memory are interconnected.
