I think it's a very happy thing to start a business. Although many times we all end in failure, I agree that you must do what you like when starting a business. Why? Because when starting a business, you are helpless in most cases, and you have to suffer much more than your friends at work. So the only belief that can keep you going at this time is that you like it? Maybe he can't bring you money and profit, but he can bring you spiritual satisfaction. You are happy to do such a thing, not even for money, so if you choose something you like and can start a business, it must be a happy thing.
