I prefer completely different working environments for different tasks. If I’m solving a difficult problem or playing with design ideas, I tend to work at home where I can control the level of noise . When I’m working through a list of small testing tasks, the noise and energy of a busy office can be just what I need.
What’s more, the change of scenery and the physical act of moving between locations is an effective way to clear the mind and reset when switching contexts. If you don’t have a choice of locations, try going out for a short walk instead.
