If human brains can be mapped to processors, I will definitely have a single core processor. I have a one track mind. I can only focus on one thing at a time. I see people working on many things at the same time. But I cannot do them like that. I work like a serial computer. My algorithm goes something like this: 1. pick a task based on priority 2. work on it 3. if success goto 1 4. if fail goto 2 (unless feel undoable) Nearly 90% of my works are done like this hard and fast rule. Whenever I divert from this rule I fail miserably(in my standard). That's why when I was given a task other than my field and which required thinking from various angle simultaneously, I was frustrated and could not do it. I can only multitask to some extent in my field of work(physics, math and electronics). Another thing of my brain is I can not take more than two activities in a day. I actually don't get time for other things being involved for long enough in a particular task to finish, which due to above mentioned serial-ness takes too much time. I want to do many thing that I cant do due to the characteristics of my brain.
