My energy production is a little low, so I need to make a generator. I need to move an IC2 machine to make room, so I look through the various chests of stuff trying to find which one I left my wrench in. I look through all of them and can't find it, so then I use the yellow box thing in NEI to highlight it, run through all my chests again, and this time when everything is greyed out, I find another block for a build I hadn't completed yet, pull those out and start working on it, still not grabbing the wrench I meant to, then run completely out of power to my plantball compressors, which I have to then kickstart with an re-battery I keep around for this express purpose, to start the energy production back up, then I remember I was going to fix my energy production, go through and find my wrench again, then find I hadn't charged it after my last use, then turn off all the machines so I can get enough power to charge the wrench, while waiting for the trickle of power to charge stuff back up, I forget what I was going to use the wrench for in the first place. I go and work with the block I found in the chest, then half-way working with that, I remember and abandon the project I'm working on to go fix my energy production, then finally build the item I was going to an hour and a half earlier, then forget where I was going to place it, and spend another 15 minutes figuring it all back out again. My wife says I have ADD. I just thought this is normal.
