In Maslow's hierarchy of needs, self-actualization means self-fulfillment, growth and :

1. Biological and Physiological needs - air, food, drink, shelter, warmth, sex, sleep, etc.

2. Safety needs - protection from elements, security, order, law, limits, stability, etc.

3. Belongingness and Love needs - work group, family, affection, relationships, etc.

4. Esteem needs - self-esteem, achievement, mastery, independence, status, dominance, prestige, managerial responsibility, etc.

 5. Self-Actualization needs - realising personal potential, self-fulfillment, seeking personal growth and peak experiences.

Self-actualization

"What a man can be, he must be."[10] This quotation forms the basis of the perceived need for self-actualization. This level of need refers to what a person's full potential is and the realization of that potential. Maslow describes this level as the desire to accomplish everything that one can, to become the most that one can be.[11] Individuals may perceive or focus on this need very specifically. For example, one individual may have the strong desire to become an ideal parent. In another, the desire may be expressed athletically. For others, it may be expressed in paintings, pictures, or inventions.[12] As previously mentioned, Maslow believed that to understand this level of need, the person must not only achieve the previous needs, but master them.

Choice (2) Learning

Option1.Affection

Maslow (1943) stated that people are motivated to achieve certain needs. 

The earliest and most widespread version of Maslow's (1943,1954) hierarchy of needs includes five motivational needs, often depicted as hierarchical levels within a pyramid.

This five stage model can be divided into basic (or deficiency) needs (e.g. physiological, safety, love, and esteem) and growth needs (self-actualization).

SELF-ACTUALIZATION+ LEARNING=SELF-FULFILLMENT
