Earlier quoted context omitted.
This cannot be emphasized enough. In a social+technical work environment, the more you "persevere" on your own, the more you'll become pigeonholed as a tech guru who solves immediate problems but loses influence in the higher-level decisions of your organization. There's still a balance, though, as asking for too much help will lead to resentment and people just straight up thinking you're stupid.
I'm not sure it really is a good thing that being too good at something is leading to pigeonholing. It's a shame that what was before (or for other discipline) named mastery is now just seen as relegating from higher levels. Can you pigeonhole in medicine? Nuclear physics ? Professional football /sports ? Cooking ? I could go on. I'd frankly rather have people with less high level view and more knowing what it really…
People who are good at something tend to ask for help when they need it. Asking for help is a way to get better. Blindly persevering wastes time and tends to force one into dead ends.
