לא ימשח אדם מנעליו ביום שדעתו לילך לדרך
you shouldn't shine your shoes on the day you go on a trip.
What is the idea behind this?
The sefer Tav Yehoshua about "Hanhagos haAdam" (how a person should conduct themself) quotes this line verbatim in "laws of keeping your body and soul healthy with clothing and shoes" siman 17: si'if 8th.
(see line highlighted in all yellow)
Based on the sefer's placement of Rav Yehuda HaChassid's teaching in "laws of keeping your body and soul healthy with clothing and shoes" perhaps one could suggest that the reason for his teaching is health-related.
