This is what someone once said to me, when I was dreaming of starting my own business. I’ve had ambitions and goals for entrepreneurship since high school. During my military service, I formed a team with five fellow KAIST students and spent a year and a half taking on a startup challenge. I used every bit of free time—personal breaks, holidays, going out, overnight leaves—to develop a construction equipment sharing platform and technology, and even tested it in the real market. But the things people said to me during that process cut deep. As I kept wondering, 'Am I really able to do this right now?', my confidence gradually faded.
