Entry into adulthood involves two major tasks: exploring possibilities for adult living and developing a stable life structure. The twenties represent the novice phase where a gradual transition from dependence to independence should occur. Young adults must create an image of the kind of life they want, especially regarding marriage and career.

Career and work present significant challenges. Entering work life brings apprehensions about different adjustments, proving one's competence, and dealing with performance expectations. Young adults must cope with competition and manage expectations from both employers and themselves. This phase also marks the beginning of new roles and responsibilities.

Marriage requires substantial adjustments. Young adults must know their partner, cope with each other's likes, dislikes, tastes, and choices. If both partners are working, adjustments are needed regarding sharing roles and responsibilities at home.

Parenthood can be a difficult and stressful transition, even though accompanied by feelings of love for the baby. The experience of parenting is affected by factors such as the number of children, availability of social support, and the happiness of the married couple.

Overall, becoming an adult means being responsible, mature, self-supporting, and well integrated into society, with the assumption of adult roles directed by one's social context.
