With focus you achieve more.
How many balls can you juggle? I can juggle two balls, but I have to concentrate and I will still do it badly.
My opinion is that multitasking is a fiction. The brain is good at focusing on one task, but only capable of doing other tasks if it does not have to think about the other tasks. To do a good job you need focus, and though I have tried to do other tasks at the same time, it goes wrong. Try cooking a meal and then concentrating on reading a book, you may remember you were cooking due to the smoke and smell of burning.
I have cleared all my tasks today to concentrate on an urgent matter. I figure if I give my full attention to this matter, I will stand a better chance of resolving it.
Do you consider yourself a multitasker? Is focus better than trying to juggle more than one activity at the same time?
