You are assuming that every low inhib incel didn't start off as high inhib, and based on my personal experience and talks with other incels that is the usually the case, this is why I find the "high inhib" excuse to be nothing but nonsense, if you want something and I mean REALLY want it, nothing as petty and insignificant as "I feel embarrassed" or "I feel weird" will stop you
You have to see how insignificant such a thing is when it comes to "true desire"
I mean if you were going to win a million dollars, 100% guaranteed, but you had to sing a song you hate in karaoke on live TV, would you be like - "nah I'm too shy and embarrased, I'll pass on that million"
JFL, I still have "stage fright" and I'm not passing that shit up
You are really just treating the things that you claim you want from life as "not essential" and that's why inhibition is a factor for you, you see the things that lie beyond your "low inhib mindset" as "I can do without it", so long as you see things that way, you won't put any effort towards getting outside of your comfort zone
The convenient thing about your comfort zone is that once its violated, you adapt, and what once made you uncomfortable, over time becomes normal
