Have you tried affirmations, visualization, incantations and so on?
If they didn’t work for you (and they don’t work for most people), it’s probably because your brain is holding onto something that’s conflicting with them.
Now you’re probably wondering what can conflict with them.
Think about it as stacking rocks.
On one side you have your affirmations, visualization, incantations..
On the other side you have the things that are opposed to them and keep you in a loop of taking 2 steps forward and 3 steps back.
So if you really want to manifest change, you need to get to the root cause.
