It is possible to multitask. You can do more than one thing at a time. I drive and listen to audiobooks daily.
What you cannot do is multifocus. You cannot concentrate intently on two things at the same time. Your mind will switch back and forth between the two. We think we are saving time, but ironically it takes more time.
If you want to do great work, you need the ability to focus on one task a time. Clarity of mind allows for focus. Focus allows for true progress to happen.
You know what it feels like to spend hours working on something yet feel like nothing changed. The great thing about focus is when you are intentional, real momentum happens.
It will take you longer if you multitask. You are not as efficient as you think. You are working harder not smarter.
Make your list and focus intently on the highest priority.
Your greatest asset is your time. Focus and use it wisely.
