itās something about preserving energy & thoughts channeling them towards something else, an assignment, project, goal etc. canāt be fucking all the time every free time you get.
Why are you making the assumption that kudinyana na assignment, project, goal etc are mutually exclusive? Issue ni discipline. Mimi hudinyana twice a week; midweek na weekend. My thought processes are usually much clearer after kudinyana. In any case, huwa nadinyana well past midnight when nothing else meaningful can be done.
