Consider these scenarios and the similarities in them: You keep eating healthy food during the week but when the weekend comes, you diet mainly consists of junk food; You wake up early during the weekdays, but on weekends you tend to wake up late, thus losing your productivity; You have implemented a healthy habit of drinking water while you work, but you “forget” this habit when it’s the weekend.
If this is you, then welcome to the club! I have experienced these same things myself. In fact, I felt I wasn’t honest to myself. I was living with the productive and healthy habits only 80% at a time. I knew I had to change. Otherwise the remainder 20% of the time would ruin my good habits and the benefits I got from them.
