Never entertain conflicting fantasies:

For example, fantasizing yourself as the richest man on earth and fantasizing yourself as a poor hero. Your reality will come close to the less advantageous of the two.

For example, fantasizing yourself as having a stable or harem of lovers and fantasizing yourself as a successful loner. Your reality will come close to the less advantageous of the two.

For example, fantasizing yourself as a savior and fantasizing yourself as a popular victim. Your reality will come close to the less advantageous of the two.
