I was watching 'Suits'. I encountered this
Mike: This woman had her life ripped apart. You don’t even care?
Harvey: I’m not about caring. I’m about winning.
Mike: Why can’t you be about both?
I could understand what Harvey says : I'm not interested in caring. I'm interested in winning. (That is what I understand)
I don't exactly understand about 'about' in this sentence.
Plus, you can also find out be about in the next sentence.
What does 'I'm about noun' mean?
Could I get more examples?
