Michael, glad you liked them.
Bhouncy, so glad you have been inspired.
I can definitely empathise with the examples you have given...I often have to remind myself not to obsess, and can easily find myself closer to the despair end of the belief continuum!
It occurred to me that the way to keep the 'middle way' may be to use our feelings as a guide. I can just FEEL when I'm obsessing...it feels tight and uncomfortable and my mind is racing as I try to solve the problem. Lack-luster feels lethargic and heavy and pessimistic.
These feelings I've realised are my biggest clues I need to shift my thinking a bit. They often set in long before my mind realises what it's doing, so I guess my work would be to start noticing them a bit sooner!
Well those are just a few thoughts. Good luck with persevering with your project.
