Heaven or Hell

After a long day at work I sit down to listen to my stereo and behold the seas part and yes Virginia there is a Santa Claus the Stereo Gods have granted me a rare evening of audiophile heaven but now I ask you why cant I stay in this state of rapture as the following day at the same time listening to the same music the seas refuse to part and Im here in a state of disbelief. Can anyone tell me why its so hard to stay in that elusive zone? Explanations appreciated.
