You have two fundamental aspects to your nature. You have a personal mind, which is associated with your body, a mind that has been conditioned by your cultures, your society, your families and by nature itself. This mind is driven by the need for survival. It is driven by the need for security and for resources. It is fundamentally fearful because it is so very aware of the risks and the prospect of loss in the future. It is haunted by this prospect of loss, and it is governed by the need to offset these risks.
What is fulfillment? Fulfillment is fulfilling what you came here to do. Only Knowledge knows what you came here to do because Knowledge was put within you by God.
When you are young, you look at the world with greater expectations. You look for what could be meaningful to you. You look to try to understand your environment.
