The secret, if I know anything about the secret, is not to eradicate doubt at all. Invite doubt. Throw open your doors to not knowing entirely. Welcome so much doubt that you get used to it; learn to stop reacting to it with such panic or dismay or overwhelm.
Doubt is everywhere, forming crevices in every thought, belief, feeling, sensation.
You can't get rid of that any more than you can get rid of air.
Yet sometimes an airlock is good, sometimes a ziploc bag, sometimes a vacuum cleaner, and so on.
Give your immune system something to work on. Pick up dirt. Do a Tarot reading, read the science paper behind the findings. Talk to someone who has little idea what they're saying, but thinks you need instructing. Use Wikipedia and ChatGPT as if they're as good as a textbook, check a textbook as if you were embarrassed to include it as a source.
Mix it up.
Keep track of the fact you don't know, but a lot of stuff is true and a lot of stuff is false, and there's skill to making the bet which is which.
You think you can do better than that?
Probably not.
I'm not saying I've said what there is to know about dealing with doubt, about using critical thinking, about checking sources.
But I think you need to embrace doubt, not run from it.
Society will try to make you think you're worth less. And you'll have trouble dealing with the feeling society is right.
But you're on a better track than the usual one, and it'll show.
