Admit it, there is a weekday you and a weekend you. The first works hard all week to get things done, achieve goals, and is “good”. The second negates in just 2 days everything you achieved during the other 5.
All work and no play does make Jack a very dull boy. However, playing so hard that you have to make up for it by working that much harder is just plain frustrating. Don’t let weekend you sabotage your progress. You’re supposed to relax, not relapse.
