In the context of hardworking and attractive, it's all back to the person interests, I think. There will be some that will attracted to you even if you do some bare minimum and some that will not get attracted at all even if you work your hardest.

Personally I think that hardwork is attractive. But knowing their own value and how to put their hardwork with the right amount and place is even more attractive.
