Honestly if you're not going into academia that's a useful skill. If I'm your boss and ask you something like "if we change part 15 to be np35 instead of the current Pl-Ir we could save 40 dollars per part, what are your thoughts of the implications?" I'm not reading 30 pages of rambling. You should be able to research and give me a summary in less than a page.

I had the opposite problem: I felt a steep constitutional objection to fluff, and writing with a length requirement was hell. Not because I was being lazy but because I was already kind of terrible (raised near-exclusively on the infamous 5-paragraph, 3-point plus thesis and conclusion, template) and then on top of that could not morally write garbage filler unless it was the very last minute.

... And that's how I ended up editing on Wikipedia for 10 years where concision is the point and the real work is overwhelmingly in the research.

The bain of my early college years was writing a paper on a subject only for prof to go now cut it half, then he did it twice more.
