How to find your business idea

When I was 6 and started going to school, I already knew what job I wanted to do for the rest of my life: building pyramids. Why did I want to build such things so badly? Because I loved to draw them on squared paper, and I was good at it. In entrepreneurial jargon, in those days I had found my niche: building pyramids all over the world. But then reality busted in and showed me the truth: pyramids hadn’t been in high demand since a long time (thousands of years), so I moved on.
From that particular time on, I learned how hard building a business can be. I remember how difficult it was to find new things I loved as much as drawing those Egyptian buildings yet still wanted to do every day when out of school.
It was freaking hard.
