Having studied hypnotherapy, I have conflicting views on affirmations. They are worthless if they're nothing but words. But can be powerful if one can bring up enough emotion and mental imagery to fully believe it at that moment. Unfortunately, I've never really been able to do that.
I also think most affirmations might be more of a rational approach than a perceiving approach. Someone who regularly tells themselves what/how they should be thinking and then tries to change their perceptions to match.
The affirmations I've had the most success on were ones that were more of reminders of an insight that I "discovered". The affirmation can bring up the emotions at the time of the "discovery". Such as the "I AM" affirmation (and those related to it). But, since I don't regularly remind myself of past insights, I tend to lose a lot of them, making room for new ones. Win-win.
As for delta aspirations...
I've always liked the song 'to everything there is a season, and time for every purpose'. Yeah, i know it's scripture, but even as a kid it reminded me of even if things are bad, some good can be found, and even if things are good, some bad can be found. That to focus oneself on only the positive removes a whole other half of the world, and of what it means to be human. But I guess this fits with the "Life doesn't suck all the time" one that you posted. And hey, even if it's sucking now, there's a story to laugh about it later. (Which fits your last one. Sigh...so I guess I didn't add anything new to your idea.)
(Btw, good to see you again. Sorry that you'll be trapped here again.)
