Imposter syndrome is a normal feeling experienced by people in all professions, but it becomes harmful when you let it define your identity rather than treating it as a sign that you care about improving. The author argues that designers can reduce self-doubt by focusing on solving clients' problems instead of seeking artistic validation, avoiding unhealthy comparisons, learning from mentors, recognizing the gap between taste and skill as a natural part of growth, and reframing doubt as motivation to learn rather than evidence of inadequacy.
