When it comes to using my imagination (daydreams & such), I seem to have oddly unrealistic realistic (bear with me here) standards for some of it. Take my love of WWII history for example, I almost never imagine myself as some bulletproof soldier. Some of my favorites: Imagining I'm in a B-17 encountering heavy flak over the Italian countryside, or a lone fighter pilot in the skies of Pearl Harbor who gets shot down and proceeds to watch in horror and pain as ship after ship is damaged and/or sunk.
I rarely imagine something being easy.
