As adults, our focus is on responsibilities - bills, jobs, the order of things. Children, however, tend to focus on play and enjoy themselves. Turns out, we can learn from kids. Our minds still need distraction that has no other purpose but to allow a time of enjoyment. It's not just about breaking up the boredom or drudgery of the work task. It's about distracting the mind with something simple. And K.I.S.S. is important. It's not about texting or playing a smartphone game or watching cute animal videos; you need something tactile - squishing a stress ball, shaking a snow globe, even spinning a paperclip on your desktop (hopefully out of ear-shot of your boss). You need to take time for you and your brain to chill out. Don't rely on fish oil supplements or vitamins to boost your memory - K.I.S.S. and play.
