In the United States and Canada there is a wideheld belief that you should already know. That learning something is for other people, who don't already know, and if you admitted that you need to learn something, it is akin you admitting of being an imbecile, or a lower type of person.
Now, in some rare cases people decide to learn something, and they go as far as getting an understanding, a surface understanding, and then they stop. I already know.
I don't know of a profession that can be done well with no knowledge, but I can tell you, spiritual growth, causing your own evolution isn't one of them: it takes more work than getting a Ph.D. and you can't copy your paper from another... you actually have to do your own work.
If you every want to unhinge yourself from this commonly held detrimental belief, obviously Dark Side suggestion, you need to take pride in doing the work, and doing it.
