Personal growth as a process remains vaguely understood. We introduce the Personal Growth Process (PGP) model based on Carl Rogers's organismic valuing process (OVP). The PGP model explains personal growth as a sociocognitive embodied process whereby an individual undergoes multiple mental shifts that make up an ongoing, fluctuating process over the long term, starting from a place of psychological safety. The mental shifts occurring throughout the growth process are broadly categorized as self-awareness, openness towards experiencing and change, existential courage, autonomy/internal locus of control, taking responsibility for the self and others, self-compassion, and compassion towards others. These shifts all represent progress toward well-being, defined here as authenticity, harmony and life-satisfaction. Importantly, the model does not include only individual psychological constructs, but ties the process to one's social environment and common social responsibility.
