This document outlines 10 common mistakes that entrepreneurs make that can kill their business. These mistakes include shooting too low with business goals, over-relying on friends and family for funding, the founder acting as CEO when they lack skills for that role, focusing too much on technology over customers, trusting people who make unrealistic promises, having a short-term mindset rather than long-term planning, over-promising to investors, failing to recognize intellectual property, neglecting to protect intellectual property, and not considering exit strategies from the start.
