Founders are told to hustle, to aggressively push themselves and their visions in order to build momentum for their businesses. Founders are encouraged to bend - if not break - the rules in order to get things done.
First-time founders are thrown into the world of finance with a good deal of ignorance about the meanings and conventions of specific financial terms, combined with a culturally ingrained bias towards spinning things as positively as possible. Broadly speaking, this seems like a recipe for disaster.
