singletasking vs multitasking

Most geeks in the world will do some multitasking jobs. They really knew and experienced since they always do that everyday, let say: writing code, debugging, ym!-ing, tinkering somethin, etc in the _same_ time. When they woke up in the middle of the night, they _automatically_ turn on their desktop PC or laptop and start working on it, while tv displayed a special-program. All about stuff they like/loved and do whatever they want, in a sense of multitasking.

Just called me somethin like grey-geek, i do some technical and non-technical activity. Maybe it's just me, i don't know whether i can do multitasking or not, see that i often got myself doing some _focus-thing_ to do and ignore almost everything :D
This is good for our health, but many people will say "you did a good job" and others will say "hey, did you serious to do BLA job?"

We have so little time and much works to do, you can't do one thing and ignore another. If you do, please start using DOS and avoid Linux, stwn!
