My name is Jia Chen and I want you tell you about my childhood dream: being a problem-solver. My mom told me it was silly because it wasn't really a profession. Through the last decade, I have been a software engineer, a product manager, a repetitive student, a management consult and an entrepreneur. They appear far from my childhood dream. But I still think I am living it. Because the essence of it is to find problems and solve problems. Some times I may not solve new problems, but I always want to solve old problems in a new way.
