- 47. Get some sleep.
Believe us, itâ€™s not overrated. Itâ€™s also the one thing for your benefit that you canâ€™t outsource, program into a gadget, or take a supplement for. Studies show that lack of sleep contributes to a variety of health problems including diabetes, heart disease, and depression. It also reduces your mental acuity. On the other hand, regularly sleeping for 7 to 9 hours a night can enhance the functioning of your immune system and improve your concentration and mood, allowing you to perform at your professional and personal best.
