are you living the dream, or are you sleeping it

I'm sorry that I've obviously been a catastrophe of moods lately. I think for several weeks now I've gone from really high highs to very low consistently, all day long, every few minutes or so. I've been fighting my flesh.

my flesh is a very bad person. I wage war with it everyday. One part of it says that I need to have the new experiences, that having what I want is just fine. I'm saved by Grace. And then the reasonable part says that living for Christ and dying to the flesh is always the better choice, and will always be what I come back around to anyway.
So why waste time?
why?
