A study† found it can take 20-40% longer to finish a list of jobs when you multitask than if you work through the list in a sequence. Number your tasks in order of priority, then designate blocks of time to each. Employing the “autopilot” technique could also boost productivity – combining one easy task (like replying to simple emails) and one hard task can improve your focus. According to other productivity experts, listening to music with a speed of about 60 beats per minute, like Vivaldi’s Four Seasons: Winter, helps too. Cue Spotify.
