the week is a fractal of the year. 

this is the garden of the mind. seeds of interest, passion, ambition, joy are already placed

 the idea is to do every week, in principle, in spirit, in miniature, in symbol, or even in effigy, what one wants to have done a lot of at the end of the year. 

thus one waters and nourishes the blooms, keeps the tender shoots green

these form the actions which become habits which eventually become the self

you are what you practice
