Elay Amitay Halevi argues that doubt signals you're chasing external validation instead of embodying who you want to be. When you doubt, stop looking for proof and ask how you're not already acting like the person you're trying to manifest.

So when doubt comes up it's an opportunity for you to get really honest with yourself about the energy that you've been embodying. It's an opportunity for you to shift your energy and your perspective because it is a sign that you're placing far too much importance on the external and not enough importance on the internal. If for example you've been trying to manifest your dream partner and you're feeling doubt as to whether that's going to happen, turn that that perspective, turn that focus that you're putting on the external world and point that back at yourself and ask yourself how you have not been in the energy of the ideal partner how you have not been embodying the husband, the wife, the partner that you want to become because that's actually why you feel down. If you're focusing all the time, if you're looking for evidence all the time in your external world is because you don't 100% believe that you are the version of you who can have the thing.
