The Big Question- Finally

So after reading Animal Farm and half of 1984, I have finally figured out a big question:

Should we strive for a utopia that we know cannot be achieved, or should we rather avoid utopias because circumstances always end up worse than before whenever we try for one?

People generally believe that we should try to achieve a utopia because it is a perfect world, and everyone wants things to be perfect. But in the books Animal farm and 1984 by George Orwell, whenever a group tries to achieve a utopia, the government ends up gaining even more control than before by making the people believe that it is for the best. So should we try for a utopia even though we know that it is actually impossible to have a perfect world so it might just be a waste of time and effort? Or should we avoid utopias altogether because whenever we try for one, the government gains even more control, lies to and tricks the people into believing that everything is just as they wanted it, and things are even worse than before with the people having even less say in things and not even realizing that it has happened? I hope to figure out which would be the better course to take throughout the rest of my study of these books.
