This is always true: What I think and how I feel, and what manifests, is always a vibrational match. But here's the big kicker: What manifests isn't manifesting instantaneously. So, you've got all this buffer of time leeway that makes you sloppy... If you thought a negative thought and a brick would instantly fall on your head every time, you'd clean up your thinking.
But you're not here to be punished about your thinking.
You're here to use your thinking—and your focus—to create.
