In Maslow's hierarchy, lower-level needs (physiological, safety, love/belonging, and esteem) are considered deficiency needs, which arise from a lack of something. Once these needs are met, individuals can focus on growth needs like self-actualization, where they strive to become the best version of themselves. Understanding needs is crucial for various psychological fields, including motivation, behavior, and mental health. Meeting basic needs is a prerequisite for addressing higher-level needs and achieving overall well-being. Tune in and learn how unmet needs shape you and healing those needs later on in life!
