As an ex-Electronic Engineer, I'm very familiar with the effects of Positive Feedback in electronic circuits. The Schmitt trigger is a classic example of a slowly-changing input resulting in a suddenly-changing output.
While I was chatting to another visitor in mum's nursing home yesterday, I had a "Eureka!" moment. I was talking to her about my sudden mood changes when the bleedin' obvious suddenly occurred to me.
When my mood starts to fall, I start doing less. This lowers my mood further. This forms a vicious circle and my mood suddenly falls to a low value and stays there, with me lying in bed/on the sofa feeling like crap and not blogging.
When my mood starts to rise, I start doing more. This raises my mood further. This forms a virtuous circle and my mood suddenly rises to a high value and stays there, with me walking, scrumping, photographing, Zumba-ing and blogging all about it.
So, do something that you think you can't do. You'll feel better for it!
