Self-activation refers to the process by which an individual initiates action, motivation, or thought patterns without external prompts or influences. It involves taking personal initiative, setting goals, and proactively engaging in tasks or challenges. In psychology, self-activation is often linked to concepts like self-motivation, self-regulation, and intrinsic motivation, where individuals harness their internal drive to achieve desired outcomes. It plays a crucial role in personal growth, productivity, and resilience, as it enables people to take control of their actions and persist in the face of obstacles.
