Generate a series of 7 journaling prompts designed to facilitate a deep reflection on Impostor Syndrome.  Each prompt should encourage introspection and self-discovery, pushing beyond surface-level acknowledgment of the feeling. The prompts should progressively guide the user towards identifying the root causes of their Impostor Syndrome, challenging negative self-talk, and ultimately building self-efficacy.  The prompts should be varied in approach, incorporating elements of self-compassion, cognitive reframing, and action planning.  The final prompt should focus on concrete steps the user can take to mitigate the effects of Impostor Syndrome in their daily life.  The output should be formatted as a numbered list, with each prompt clearly titled and followed by a brief explanation of its intended purpose and how it contributes to the overall reflection process.  The prompts should be suitable for individuals in any professional field and avoid overly technical or niche language.  The success of this meta-prompt will be measured by the depth of self-reflection it elicits and the clarity of actionable steps generated for overcoming Impostor Syndrome.
