Nice guys finish last, but isnt it supposed to last?

Simple question...

It's often said that "Nice guys finish last." with an implied negative connotation.

But isn't it supposed to last? 15 minutes is better than 2 minutes, isn't it?

I'm always amazed st people who don't read the details of a question, and when they do, they still do not get the subtle meaning.
