Good. Supposed Nyom has bought a car. After a while it gets broken here, broken there, first cheap it requires a lot of tax and fuel. He comes to late. Sometimes does not reach the place. And when one day starting to think more correct, he sees that the cost are much higher then any benefit. Would he another time go and let it be repaired? Would he fill risky another tank? Or would he just drive till there it would then stop. Step out and leave it behind?
Or if Nyom falls in love with a woman. Invests much, time, effort, thoughts, labor, 1000 of hours for some minutes, and again, again, struggle, cheating... and one day he starts to calculate serious and truthfull and sees that the pleasures gained aren't even 1/1000 of the sacrifices. Would he further but ony labor into it, maintain and sacrifices for such a relation, or simple let it run out?
Or a shirt... form, sound, smell, taste, touch, idea. If seeing that there isn't any refuge in it, subject to decay, would he give a penny into it if required to steal it or cause harm, fight with another blind?
Yet if even seeing on the other side, while still busy with useless, things worthy to give into, supportive, a refuge, a raft to cross the swamp, would he put a penny of conflict and struggle, fight and even grave wrong to maintain useless stuff?
