A lot of these online advice things are based on the assumption that the underlying problem that's holding someone back is the fear of failure or rejection and try to motivate and rationalise you over that fear. For me that's not the problem, I'm ok with failure and rejection, have a lot of experience with it.

Fear of success they sometimes hint at and that's at least partially true.

Fear of ruining someone's day and being blind as to when that may be the case is more accurate for me.
