Growing up without positive encouragement can shape individuals in various ways, both positively and negatively. For instance, it can instill a fear of failure, perfectionism, shaky self-confidence, and a constant need for validation. Such individuals may also find it hard to accept praise or criticism, develop strong self-reliance, and possess a determination to prove themselves. These traits often stem from a lack of support and encouragement during childhood, leading individuals to rely on themselves for validation and success.
