Each truck has its own capacity: a mini-van carries less than one of these huge hulks. It all depends on the load area and the volume. But not only! Sure, I can only load as many wadding packages into a truck as there is actually room for - but: I may not be able to load as many lead packages as there would actually be room for. The lorry has a limit not only in terms of its volume, but also in terms of the permitted transport weight. In other words, I cannot load as much as I like, but have to consider both the filling quantity and the filling weight. It is similar with our human possibilities: there may be time capacity, but the matter at hand is mentally very stressful. For me, too, we have to use our resources wisely so as not to overload ourselves and others. I wish you the wisdom to do this today.
I wish you an extraordinary day!
