You are very lucky if you can guess(know how) if the prices will go up or go down, if you can succesfuly follow the trends and make money from it. I say that because there are many people out there that can not do that and they can not make money also. So if you have the money you are able to think for other important things in life like the "good emotions" you say. And this way must be. But if you do not have money then things are different ... very different ...
