Why do I try to make paper clips last?

This is really dumb. So if you use regular paper clips to stick pages together, you’re probably used to them being slightly bent out of shape after using them a few times. Then I try to make them last longer or using them while they’re not really that useful anymore. Why am I doing this? They are cheap as fuck. And there is still like 2/3 of them in the box of 100 I bought six months ago
