2 or 3 years ago I used to read some of an internet-famous person's blog posts. They were mostly economical and entrepreneurship related and I liked the way they were written.
Ever since, I stopped reading his blog since his personal growth "road" has taken him into some strange areas I don't really care to follow.
For example, there were some traces of some kind of mysticism, and then he decided he should separate from his wife, then try polyamory and this year he's going into BDSM !
I know the last part since I re-open once in a while his link to see if something interesting might pop-up. Imagine my surprise when I read his latest blog post...
Of course, it could also be some cultural blocks that deny me to see the "value" in what he's is trying to achieve, but I think at some point personal growth might be able to turn malign.
Humans aren't really built for infinite growth given the simple limitation that people die. So, it might be that trying too much to "grow as a person" leads to desensitizing towards normal life. Which means that it's possible to start using more extreme "personal growth" experiences to make up for it.
