Consider a small business owner, who works non-stop. However, working hard won’t help him compete with his multi-million competitors. Time is a limited commodity. An entrepreneur can work 24 hours a day and 7 days a week (the most amount of time anyone can work, really). His or her competitor can always spend more money, build a bigger team and spend a lot more time on the same project. Then why have small startups accomplished things that larger corporations couldn’t? Facebook bought Instagram, a 13-employee company for a billion dollars. Snapchat, a young startup with 30 employees is turning down offers from tech giants Facebook and Google. Part of their successes were based on luck — the rest is based on efficiency.
