My idea of of positive thinking is when you truly feel inspired to start something, not because you 'need' to and are thinking of xzy reasons why it has to be accomplished, but when the inspiration propels you into the zone of knowing you can do this and that it feels right. That feeling is unique and to me is precious as it has no strings attached or conditions on what might happen if it fails etc. So in other words it is not formed out a fear to accomplish something but knowing you just can.
Interesting. This fits in with my post where I "decided to cure him" not "thought I might be able to", or "would try to", just "I would" no doubts about it. Possibly the power of positive thinking?
