And another AHA! moment... I realized I have been intentionally manifesting things in my life since I was 8 years old. I just didn't know that's what it was called at the time. I would concentrate and focus very hard on something I wanted (usually an experience, not an object), go into a semi-hypnotic state, and it would happen. If my intention was not positive (one time I wanted revenge for being hurt on the playground), it wouldn't work.
No wonder I'm having so much fun with this. It's like being a kid again.
