Writers say that creative writing means transforming into a trance-like state.
And that is only possible during the actual process of writing. I also love to write while traveling abroad. But, truth be told, it's more efficient to write at home because whatever I jot down away from my desk eventually has to be keyed in on my computer.

Runner-up would be to work in some remote area in a forest.
