One of the biggest mistakes I see in manifestation is constantly checking if it's working.
You affirm, visualize, script, then 10 minutes later you're checking your phone, your bank account, your circumstances, looking for a sign that something has changed.
I've done it too.
The problem is that every time you go looking for proof, you're coming from the assumption that you don't have it yet.
If you ordered something online and knew it was on the way, you wouldn't spend all day wondering if it exists. You'd simply expect it.
Manifestation works the same way.
Your job isn't to force it, chase it, or keep checking on it. Your job is to become familiar with the feeling that it's already yours.
The question is: if you truly believed it was done, what would you stop worrying about today?
