Sleep

• Stick to a consistent routine. If possible, don't use an alarm to wake up.
• Don't use screens before sleep or right after waking up.
• Avoid sleep disruptors. Don't drink a lot of alcohol, don't eat large meals right before bed, don't have caffeine past mid-afternoon, don't watch super-intense movies right before bed, etc.
• Spend the time to find the mattress, pillow, and sheets that work for you.
• Exercise.
• Resting well is one of the highest compounding life habits. Makes everything else better. The better you rest, the more you enjoy life.
• Sleep in a dark and cold room. To lower your body temperature you can take a bath before going to bed.
• Don't stay in bed if you can't sleep.
