From Why You Should Seek Quiet Every Day by Herbert Lui:
Every day at around 3PM, my brain gets weary. I’ve tried numerous techniques to counter this challenge:
– Coffee (especially when McDonald’s was giving away free smalls)
– Splashing cold water on my face
– Wandering around online
Yet I’ve found one technique to be the most effective: going for a walk. The longest stroll I’ve taken is around 10 minutes, and I just wander around the block.
