Impostor Syndrome Is Lying to You

That voice telling you that you don't belong, that you got lucky, that everyone else knows more than you -- it's not wisdom. It's fear wearing a convincing mask. Impostor syndrome tends to hit hardest in people who actually care about doing good work, which is ironic: the ones who should worry least, worry most.

You don't need to wait until you feel confident to act. Confidence comes from doing things before you feel ready, collecting evidence that you can handle it, and slowly updating your self-image. Keep a file of wins -- positive feedback, solved problems, moments where you figured it out. On bad days, open that file.
