Hey Andrew,
I don’t know if you have been reading much of my recent post but I went through a process where ‘my’ high achiever personality had to use ‘his’ only tools (of being a “high achiever” 
) to give ‘himself’ no choice but to eventually get exposed.
It was messy as ‘I’ had to use all of ‘my’ best tools, which one by one were shown to be faulty. They continued hanging on in the most tenacious manner until ‘I’ started running out of tricks. Of course ‘I’ then tried to keep using those same tricks under a different guise, but eventually this also ran out of any capacity.
For the one’s inclined towards intellectualisation it seems one of the best ways you can speed up this process is by honestly writing on here, and being prepared to be happily shown as wrong over and over. It seems it is doing exactly this that led to @henryyyyyyyyyy’s success recently. It was useful when @Vineeto suggested that I throw away any conception of appearing foolish, this advice meant that ‘I’ could as if vomit all of ‘my’ inner workings through ‘my’ writings
Then it is only a matter of time until these mechanisms (such as the intellectualisation) begin to show their cracks. The ‘intellectual’ can give ‘himself’ no choice but to be shown to be utterly wrong, and eventually to realise that ‘he’ is redundant.
