Answer:
1. Curiosity. Great entrepreneurs are tasked with identifying new problems, identifying potential niche opportunities, refactoring their existing business processes, and innovating. This necessitates a passion for various fields of study and business cases that are outside of one's comfort zone.
2. Time management. Prioritization, milestone definition, execution, and iteration are all critical. None of this would be possible without the proper project management and time allocation methodologies in place to complete the work.
3. Strategic thinking. Learning to break down a problem to its simplest components and identify growth opportunities. Inventive problem-solving and spotting the low-hanging fruit. Defining an MVP's scope and testing concepts in a short amount of time and on a tight budget.
