I've been the same I've noticed, but I think it's just because I have too much on my plate all at once.
sometimes I'll remember something and think to myself "Ok I really can't forget to do that when that time comes"
sure enough, I forget.
so I have to play these stupid psychology games with myself all the time.
My apartment is full of obstructions in the walkways at any given time. These are little reminder bombs I set for myself. If I have to walk around something, I think "why's that there? oh yeah"

At work, I've gotten into the habit of writing pretty much everything down.
jumping from work to ceg every time I'm waiting for the printer or when a program is running slow doesn't help my memory much either.

I distract myself way too much.
