context is everything.
let's say i am building an outhouse. and let's say i have done it many times before, and i know exactly how to get it done quickly and to my satisfaction. now let's say there are others that want to collaborate with me on it.
collaborating with them could both slow me down, and introduce additional opinions on how it should be done, which in this case only serves to get in the way. so in that scenario, i would say collaboration negatively impacts my goal.
of course, it is possible that they want to learn from me, or that i want to learn from them. in which case, collaboration would positively impact our collective goals.
