When it comes to exercise and healthy eating, we need to create new habits. If you can implement even a small change, such as drinking more water, give yourself time to let it become so habitual that you don't have to think about it anymore. Think of it as wearing a new groove into the carpet. At first, though, you'll need some stick-to-it-ness. Line up your water bottles the night before. Do whatever it takes to keep to a schedule.
