I know someone who are very good at multitasking. They can do many things at the same time. I found that I can’t really multitask very well. I can only time-slice my tasks. When I am working on one task and want to switch to another task, I have to put down the on-going task first. I can swap tasks back and forth but it takes quite some time for me to get back on to an effective working state of the task. I found that it is easier to swap between tasks if the tasks are very different. I think human brain operates like a computer, it has different processing units dedicate for each type of tasks. The same type of tasks use the same processing unit. If you switch from one task to another, you have to first unload the old task and then load the new task to the processing unit. That can explain why my idea for writing blog entries dry up in the past few days. I have an 2000 words philosophy essay due on Tuesday. My processing unit for writing is blocked out by this demanding tasks.
