Unlike flies, you can learn new skills to get beyond the pane. Even though reducing self-confidence can be helpful, my clients usually object to modifying that part of their Personal Interiors. This is similar to when your clients object when you advise them to alter a cherished aspect of their building's interior. People usually entwine these two elements in their Personal Interiors. Parents mistakenly teach children that their self-worth is measured by their achievements.
Children learn that if they earn grades of A or B in school, they are worthy.
If they get a D or F, they are unworthy. Adults continue to clutter their Personal Interiors with the mistaken notion that their self-worth derives from their achievements. If they get a promotion, or secure a contract, or satisfy a client, they are worthy. If they don't, they are less worthy. Your self-worth is independent of your achievements.
