I have so many things to do my brain is not happy. I can't think straight. I can only think of one thing or nothing at all.
I used to say I'm good at multitasking. Not anymore. It's definitely a myth or the fact that I'm getting old.
We often think that combining tasks will save us time, but scientific evidence shows that it has the opposite effect. Even those who claim to be good at multitasking are not very productive. In fact, they are some of the least productive people. Our brains can take million bits of information but can only actually process of few dozen per second. When we say we're multitasking, what we're really doing is switching back and forth between tasks very quickly. Unfortunately, we're not computers adept at parallel processing. We end up spending all our energy alternative between tasks, instead of focusing on doing one of them well. Concentrating on one thing at a time may be the single most important factor in achieving flow.
