mindset can work as a self-fullfilling-prophecy
example:
you think you got no skills in technical stuff. this leads to situations where you avoid to get skilled in technical stuff (your computer got a defect-you call your brother to let him repair it etc.)
5years later you really got no skills at all in technical stuff.

example:
you see a girl in a bar, want to flirt with her but your pessimistic mentality is telling you that she will not be in the mood to flirt with you. however , you are trying to flirt with her. but you will do it in a way that is not fun for her and you cause you are building resistance out of nothing. so the effect will be that she is really not in the mood to flirt with you.

how is this affecting your poker?
example:
you think you are always getting sucked out when you hold aces. so you dont raise the flop aggressive cause you will loose probably anyway to some donk holding 63off not respecting your raise. because of your lack of aggressiveness someone got a greater chance to break your aces.
