How can someone differentiate between healthy self-assurance through positive self-talk and a reliance on external validation from others when overcoming self-doubt and uncertainty?

Healthy self-assurance through positive self-talk involves building confidence and belief in oneself through affirmations and self-validation. On the other hand, relying on external validation from others involves seeking constant approval and reassurance from outside sources to feel confident. To differentiate between the two, one can assess whether their self-assurance is primarily coming from internal sources or if it is dependent on external validation. It is important to focus on developing self-confidence from within rather than seeking validation from others to overcome self-doubt and uncertainty effectively.
