I wanna tell you "right time" to start a business. I said that, today, the world has changed. That is, it has changed from "analogue" to "digital". We'll live to be 100, with the technology to manufacture medicines developing. So someone will have to do a business at leat once in his or her lifetime. Then, when can you begin to do a startup business? From an expert's point of view, first I wanna tell you to do it until you're in your mid-30s. If you think it is hard, you can have the second chance of doing so when you're in your mid-40s. Unfortunately, if you miss this opportunity, you will be able to do a startup business when you're in your 50s to 60s. If you fail to do so, you have no choice but to be directed by others. Nowadays, Korea has the "optimum" environment where one can do a startup business. That is, the Korean government is providing sufficient places for them, and at the same time, it is supporting them financially. So they don't have to borrow money from banks or somewhere when starting a startup business. If you have an idea, I'm very sure that you will be able to do it!
