Pointing a thread to the east, you practice your navigation skills. You’ve discovered a method to tell direction using just a thread, so you point it to the east in order to find your way. The method takes practice though, so you’re sure to practice every day.
Also, you are Ren (れん), from Ren & Stimpy the TV show. Since you’re not in the TV business anymore, you’ve decided to practice your other skills. How mature of you, Ren.
