I hate it when I'm totally focused on something and I keep getting nagging distractions, like the IM window flashing, etc. It totally breaks my concentration and I can't zone it out like an N might. My concentration feels broken up into a million pieces, with a staccato beat.
Also, I hate it when I'm trying to do something full-speed and I hit speedbumps like slow software, etc. It irritates me and makes me feel like it takes at least twice as long to do something, even if the interruptions only technically take up a portion of the time. It's because I'm always gathering momentum, and if nothing stops me, I end up going lightning speed... kinda scary, actually.
Any other SPs ever feel this way?
