follow a road that goes nowhere

I always had the impression that our destiny is determinated. Even with good studies, we will not have a real future. We will just follow a path. It’s difficult, and sometimes impossible, to create his own path. Well, it’s my impression. Platon (I think it’s him) said that “there is no favourable wind for the person who doesn’t know where she goes”. But sometimes I would like to give up doing all the things I’m doing, and follow a road that goes nowhere.
