I have done that. It always helps and occasionally a different idea pops in too. Many times, I just watch a movie (or play games) with similar ideas or actions (for example, Last Full Measure, while I haven't watched Aliens in a while, I have watched Starship Troopers while fighting with a chapter, as well as replaying Mass Effect (two other inspirations for it). (Have watched videos on YouTube, too, for both historical accuracy and some psychological accuracies too.)
