Gretchen Rubin Quotes
Get enough exercise and sleep: Sounds trivial, but it's not. You may have the urge to work 24/7, to skip the gym and to stay up late to get a few more things done. That's short-sighted. Exercise and sleep are critical to having the physical and mental energy necessary to meet a challenge.
