If you really want to do one thing, then you must be ready before, when I started going to open a company, I do not want to buy things such as router or outdoor, they say you want to go see your company is outdoor router, I said in fact, sometimes I do not know my company need what kind of things, but they have some very professional advice, I certainly will listen, because you would not understand those things, then you must listen to what they say, in fact, I think sometimes you also have your own ideas can, not because of what they say what you have heard.
