I will assume that you either dont know how torrents work in principle, or you don't care. For the time, I will assume the first but time shows our true selves.
In case you didn't know, the 3 torrents you downloaded so far, came from other members of this forum. Are they "crazy" and "insane" too for keeping torrents alive for you and others to download? Think about that for a while. The fact that people are seeding is the reason we find software to download and at good speeds with most torrents at least.
The 72 hours is not continuous but they do need to happen within a week. Seed some now, some later but you need to seed (keep the torrent alive) for at least 72 hours or 1:1 ratio. We understand if you don't like it but the general rule here is, if you don't like to share with others, others won't share with you. That simple.
In the end, it's not like we ask you for something dramatic. Let your torrent client on and do whatever you are doing with your PC.
