Getting 1000 views in one day is quite possible, in fact there are writers on this site who get more than that. But how that's done is going to vary from writer to writer.
Some writers will find they can create a single quality Hub which can draw that much traffic. For others, that much traffic might come from the combined attraction of several Hubs. And for other site members, it might take them dozens or hundreds of Hubs to achieve those levels.
It's going to vary with writing skill, chosen topic, audience interest and more.
