1. Sleep at least 8 hours

Many studies talk about the importance of getting enough sleep, because the brain needs time to recover, consolidate memories, and store the information it has absorbed during the day. Lack of sleep is a major factor in cognitive decline.

Bill Gates once said that, early in his career, he slept very little and thought it was not a priority, but he soon realised that lack of sleep was affecting his creativity, productivity , and more, so he decided to have a nightly routine (starting with washing dishes to relax his brain) to get adequate rest and sleep each night.
