Negative self-reflection and self-criticism can vary from individual to individual and may not necessarily decrease after puberty. While some people may become more confident and self-assured as they mature, others may continue to struggle with self-criticism. Factors such as personality, life experiences, and mental health can all play a role in how individuals perceive and criticize themselves, regardless of their age.

Self-criticism and perfectionism are closely connected as they both involve setting high standards for oneself and being overly critical of one's own performance. Perfectionists often engage in self-criticism as they strive to meet their unrealistic standards, leading to a cycle of never feeling good enough. This constant self-criticism can also contribute to the development and maintenance of perfectionistic tendencies. Ultimately, the connection between self-criticism and perfectionism lies in the relentless pursuit of flawlessness and the tendency to be overly critical of oneself when that standard is not met. **

Additionally, surrounding yourself with supportive and encouraging people who believe in you can help boost your self-confidence and provide a source of validation. **
