D'aww thanks! (I had this tab open for days and only just realised)

Haha, sorta... I mean, if you go under the theory that "nothing is true unless it happens" then we're always lying to ourselves when we try to predict the future.

It seems that your approach is a flexible one, where truth is more of "what you make of it" (= self fulfilling prophecies). I definitely agree to an extent with the "Law of Attraction"-like stance, even though I can't stand people who swear by that book/rule.

My explanation as a basic psychologist is not one of cosmic energies, but simply a matter of attention:
We take a person having a day. That day has a lot of frustrating events, and also opportunities/fun moments.
That someone who is pessimistic/annoyed/angry, will notice all the things that anger him (e.g. my bike pedal loosened 2 days ago), so much so that he will miss the opportunities/pleasant events. (e.g. one day I was biking to work and I noticed a quirky salamander on the side of the path. Another, my flatmate walking to work)
Someone who is hopeful/energized/determined will ignore the noise and pick up on the opportunities given. An opportunity could be a small smile from a stranger (a new friend?) or perhaps, someone on the side of the road who needs help.
Having gone through the same day, the pessimist will say how lousy it was, whereas the optimist will say what a great day he had. They will both be right, subjectively and objectively because of what they engaged their energies in.
Thank you for coming to my TED talk :)

Lucky you! Talking slow is bearable - I hate knowing that I know a word, but being incapable of retrieving it. Or retrieving a typo'd cousin of the word I'm looking for. ("right to bear/bare arms")
