What you can do to be happy and a good person?

According to Aristole we will be able to build a Happiness Machine, where this machine may take us to a perfect life, we wont even know if it is reality or illusion and we will be happy the rest of our life. But there is a failure with this Happiness Machine, what would happen if people just wake up from the Happiness Machine and realize that everything was a lie? Well people would be really sad and disappoint becuase everything they thought it was a lie and that anything of that was reality. In the another hang you can be a good person by doing what a good person does, according to Aristotle, and you will reconize a good person once you see it. I think that human are born with the ability to reconize when something is good or bad, that why you can reconize a good person when we see what is that person doing, and we will be able to say if his or her actions are good or bad.
