One way to improve sleep is to go to bed, and wake up, at (or around) the same time every day. Many people drastically change their sleep habits from day to day, or between weekdays and weekends. Our bodies would prefer a predictable routine.
We have more willpower available to us when we are motivated and determined. We are more committed when what we’re striving for is tied to our ideal identity, who we would like our future self to be. It’s important to ask whether our goals are actually ours. At times, we get caught up in what we feel we “should” want, or what others want for us.
