You know how powerful a laser is. Immense power can be focused on one area. Human focus is the same. We can do more than one thing at a time providing they are not too difficult or don’t require concentration. We can do one thing very well if we focus our attention. Driving and texting can be a fatal decision. Some of the world’s most talented people have learned to focus their attention on one activity.
Try giving your full attention next time someone speaks to you. If your mind wanders, just pull it back into focus. Try the same while driving. Just focus on driving. Try doing everything you do with full focus and undivided attention.
