Easiest way out of that is to commit the Genetic Fallacy: Consider the speaker first. A broken clock can be right twice a day, but the main point here is to identify who is doing the speaking, to separate the advice from the advisor. It's not worth getting hung up on every do and don't from every quarter, given that every artistic goal out there is likely not going to mesh with your own, much less overlap in some area or other. Most folks are likely going to have no idea what motivates you, interests you, even in some cases if they've known you for awhile. Most folks aren't physicians when it comes to anything, much less getting you in better shape to improve on whatever it is you do. And there are plenty of didacts out there, managerial or otherwise, who are more than willing to get you spinning your wheels so as to satisfy some need or goal of theirs, while burning you out in the process. Are those temple steps that they're ascending, or a ladder? Because only one inclines gradually and allows for others to be alongside in the ascent without being pushed out or stepped on. And only one doesn't require others to stay put below while steadying the base.
Maybe that's a bit utopian to expect a wider path to be anything but hierarchically disorganized while everyone is climbing it, or that a narrow path can entail honest ascent without greedily shoving out others (not to mention that steps are set in stone, while a ladder is adjustable). But I think once you consider someone's aims, their goals - or as is likely, their industry institutionalization - you can probably better consider whether you'll come closer to your goal given you take their advice and internalize it.
And note, internalize. This should probably go for the whole process of consideration as well. Keep thy own council.
As always, this is all off the cuff, and not thought out.
TL;DR: Develop your BS Radar. Preferably by not being over-eager or a production hero.
~NBB: ...Well that was interesting. Spent a while paragraph saying some things aren't worth spending a whole lot of time thinking over.
And in my best Mike Stoklasa voice: "Now think about *that*, you mutherf*cker, you!"
