Curious because there is a lot of crap out there [see self help aisle(s) in any book store or public library].
As for me, my motivation and discipline fluctuate and cycle rapidly beyond my control, due to bipolar, so I always feel I need adult supervision before I go running off into the woods with a pair of scissors; which I've done more times than I'd care to admit.
Currently seem to be on the low ebb of the thing after spinning out of control last month. Can't even seem to complete a thought or a to-do list right now, and feel like I'm walking through quicksand in a mindless haze. Can't complete anything I start or even clean up after myself. A month ago I was having rage-o-holic fits at everything and couldn't stop fidgeting or cleaning or pacing around talking to myself. In Feb. my brain felt like it was screaming, and I couldn't make it stop or get any sleep (had to go into an emergency 24 hour psych place a couple of times). Anyway, I've been coming up on Lamotrigine since then, so, who knows, maybe it will help, maybe not. It's hard to tell from within here, I need observers to give me feedback on that, I just really can't tell, and never have the wherewithal to chart my own states.
So yeah. Or no, rather, for people like me, even with some level of psychiatric maintenance and supervision, I still go funny and off the rails. Even in the best of times. In years past, with better jobs and better insurance, the bipolar thing was constantly my undoing, no matter how hard I tried or how compliant I was in treatment. And now that I'm vicariously watching my 51 year old dad self destruct (yet again) with bipolar... It's disheartening.
This last bit about my dad^ is me reflecting on discipline and motivation. He's one of the most disciplined and motivated people I know. A JD and an MBA amongst some other things that escape me at a moment, with a remarkable career(s) in law and business, and teaching. All the work and discipline in the world, even with the best health care money can buy, don't seem to do a lick of good for him, or his (also bipolar) folks for that matter. Seems to get worse with age in my family. It seems that way, but I'm looking at my elders who, to me, seem to be going apeshit. Granted, there is Mormonism (see Glen Beck) in their mix, and some toxic Tea Partying and conspiratorial thinking that may be making them unhinged. Oh, who knows.
