I am stumped. I have a sentence I wish to write but am uncertain where I can insert the caveat. The sentence is either: 'I believe, at their core, all writers are daydreamers.' or 'I believe all writers are, at their core, daydreamers.'

Which is grammatically correct?

Any assistance would be greatly appreciated.
