If you feel you are going nowhere, perhaps it is because you've never tried to go anywhere in particular. You need to have a dream - an idea of where you want to go to. The graveyards are full of people who thought they were irreplaceable. Without a life goal of some sort, however modest, all of us end up like ants - working all day so we can create the next generation of ants who will do the same. It's no life for an intelligent being.
Some modern people think it's clever to say that man is an animal, or only an animal.
Aristotle said that some men are fit only to be slaves. If you have got this far, I hope that you are in neither category. That means we have to have a reason. Otherwise we just get depressed. A goal for a single day is enough, to start with - something minor.
