The bad habits always look far worse in details, when one is forced to deal with them, and that's a powerful disincentive to working seriously on one's bad habits. One must first get over the self-conscious feelings and take things stoically, and that's difficult to manage under pressure and with tinnitus screaming in your ears and all the rest of it.
Establishing a pattern of good habits disturbs the ecosystem of bad habits. The gremlins and ghosts in one's cognition like things the way they are; their simple needs are periodically met under status quo so they don't like changes.
It's been ridiculously difficult, like... embarrassingly so. It's taken years of trying to get any good habits established.
