I understand what you're trying to say — I've felt similarly before — but I don't think that statement is always true. I think people in general are adverse to painful or uncomfortable stimuli, like when we get flooded with anxiety before a presentation or asking someone out on a date, so a fair share of the time we do everything in our power to avoid it. Now, take people like us who have similar or the same before, but magnify it 100x or 1000x. After years of experience, we have these maladaptive thought patterns and emotional responses to things and they're so ingrained in us, we don't know we're doing it 99% of the time.

I know I've felt that many times with my social anxiety: getting into pretty much any social situation triggers a physiological response and I become anxious, which then cues automatic negative thoughts, and unless I challenge myself I'm almost guaranteed to pull away or avoid the situation before it even happens. And every time this has happened, it's reinforced failure, not success, and it's become a self-fulfilling prophecy essentially, which has made me miserable in the long run. But I've also found that if I've pushed my boundaries and tried to expand my comfort zone, that discomfort has eventually dissipated and I've generally had a good experience.
