Ben aslında bir yöneticiyim.
- I'm an executive at heart.
O, aslında iyi bir adam.
- He is a good man at heart.
My dad may be old on the outside, but he's young at heart; he plays video games every now and then to improve his coordination.
He seems to be very angry all the time but at heart is is a very gentle person.
... Expertise is at the heart of all progress, right? ...
... along these modern roads in the heart of anatolia ...
