Dunno. If you're working on something special I would understand being proud of the amount of work going into the project. For instance I'm working on an exciting business trip that's forcing a lot of late night meetings. So hell yeah I don't mind working till 8 if it gets me 3 weeks abroad. But otherwise I do know people who talk about how busy they always are but are either lying (to make themselves appear to be hustling) or don't use their time wisely.
