Sacrificing personal career development for family happiness is a choice that many people face in life. This choice is complex, with both personal emotional factors and the influence of social and cultural background. First of all, family happiness is a very important goal in life for many people, and sacrificing career development may bring improved family relationships, stronger emotional connections and a sense of stability in life. Especially in the critical period of children's growth, parental companionship and support are often considered more important than career achievements. However, sacrificing one's own career development for a long time may also lead to a lack of self-worth. On the one hand, career development can bring a sense of accomplishment, social recognition and economic independence, all of which have an important impact on personal self-worth; on the other hand, continued dissatisfaction and self-sacrifice may lead to mental health problems, such as anxiety and depression. Therefore, balancing family and career development is the key. You can consider the following ways: 1. **Set priorities**: clarify what is most important to you and set reasonable goals and plans. 2. **Seek support**: Talk about your feelings, discuss with family or friends, and find support and understanding. 3. **Flexible arrangements**: Explore flexible working methods that can balance family and work, such as remote work or adjusting working hours. 4. **Small steps**: While meeting the needs of your family, you can try to maintain a certain level of professional development, such as participating in industry activities and learning new skills. Ultimately, there is no standard answer to this choice, which depends on your values, life situation and personal goals. It is important to reflect on your feelings regularly to ensure that you can balance your inner needs and career pursuits while pursuing family happiness.
