If you haven’t got the confidence, status, good looks or whatever it is you believe you need to have, to get what it is you want, then assume you have it. Adopt the attitude of assumption. It’s very powerful.
If you’re going for a job, and you need to have this or that qualification then I can understand. Other than that it’s probably just a distorted belief, which is stopping you. They’re called ‘distorted’ for reason. Because they’re not real.
