Usually for women or those who are feminine, this special, life-long goal is a profound one for a person. It springs from their very identity, and is sufficient to see a person through, all the way to their goals. And even through great trouble, conflict or crisis. This is one of those unique features of psychology that plays into both sexual attraction, by way of femininity, and intellectual attraction, by way of being a partner with a major goal. It guarantees that both kinds of attraction are tied together.

The three factors involved with making sure a life's mission is achievable or not, rest in:

• Being naturally good at something.
• Enjoying what that something is, taking pleasure.
• What a person's life goals are in how they may benefit society (altruism.)

When one is on their "purpose in life," they have found the perfect, perhaps singular, life's goal for them - one that capitalizes on all their strengths psychologically, their beliefs and values, and since this term often is used by women, as opposed to the more common, "mission in life" used by men, the "purpose" also amplifies the woman's femininity, just by striving for it, let alone meeting the goal.

This feature of personal growth cannot be done without in a romance either, because it will be an enduring source of femininity for the woman, from which she may impassion the man and amplify his masculinity by way of the steps of sexual attraction.

One should never align with a partner, for whom one must sacrifice or in any way take away from the purpose in life. If that is required, it is the ultimate deal-breaker on the relationship, and essentially guarantees the demise of the relationship.
