When you create secrets you make realities.
You think "the reason I can't share this with the other person is because it's true and will hurt them."
This presupposes a truth and makes it real.
If you assume a thing is true, then you'll find confirming evidence of it.
Imagine you assume someone is a blowhard.
You listen to them say 20 things.
Most of them are fine, but 1 thing sounds like a blowhard.
By looking for that one thing, which you will find given enough variance and time, you're manifesting that outcome.
You expect to see it, so you do.
That creates your reality, which you take action on, which makes it real.
If you say you're a 10/10 but are actually a 6/10, you will manifest failure.
