I get where you are coming from. Frankly it’s a tricky questions to answer, because if you let nothing hold you back then any suggestion just renders itself limiting. If you are mildly ambitious and intend to progress in your chosen industry, then eventually communication becomes a big part of what you do if not top priority, whether it be managing personnels, consultation or negotiation of some sort. By the way I work in product design, and briefly thought about doing accounting back in high school because of the lack of ‘communication’.
