Cut out or set strong boundaries with people in your life who discredit you because they think that marginal self improvement is the same as past failure and unreliability. (I presume that has been and will continue to be the path of everyone here.)
“Why would I trust you if you were wrong about X in the past? You said X now it’s Y.”
“Why didn’t you just get it right the first time? By listening to the experts™️?”
Notice that these same people will hardly ever admit that they were wrong. Fiat culture has trained them to never accept personal responsibility and instead, pass the blame and cost onto others. Always slaves to the predominant and mercurial totalitarian narratives.
Our superpower is accepting Sunk Cost. Train it like a muscle.
