Dunno about anyone else but I think it's hard wired from childhood
If you're told you're not good at anything, don't deserve much, achievements not recognised and reinforced, and mistakes catastrophised because you're not up much
...it becomes a bit, well I might as well just screw up as it's expected
You're right, we do cling onto the bad
Got two potential counselling routes and pondering exploring some of this stuff there plus talking changes at some point (don't expect much from that like)
Anyway, dunno about anyone who else

*Anyone else who might think the same ways
