We all have multiple things to do at any given time. Multi tasking is simply a way of life.
However, consider the occasional sprint.
Instead of working on multiple projects at a time, a sprint is when you put all of your efforts into one project and work as hard, and as fast, as you can to get it done. Frequently this means ignoring the clock, ignoring the phone, ignoring everything until you finish.
You can’t sprint all of the time as it takes a great deal out of you so when a print is over, you need to rest and recover but knocking out projects one at a time, via the sprint method, can be more efficient than trying to do everything at the same time.
Have a great day!
