Well, i have moved a lot and I feel the same way that you do about it when I encounter all the "stuff" I have managed to accumulate over the years. I recently moved and gave away 75% of my stuff and decided to streamline my life. So the next time I move it will be easy.
But yeah, I feel ya. moving sucks. Love the "real men do it in one trip pic" I can definitely identify with that notion.
I'm actually hoping to discard/donate/sell 75% of this junk, it's one of the reasons for the move. Hoping it'll make it easier to move next time, as you say.
I'm totally a pack-it-all-in-one-trip mover.. dump in all in the moving truck and sort it out later!
