4. Efficient Transportation.
Make a list of
your groceries ahead of time, plan your day and route for doing
everything you need to do that day efficiently can make a
difference. If you pick a grocery store and pharmacy close to
your work, you can swing by on your way home. If not, then you can
still do a weekly or biweekly grocery day. If you have to drive special
to a grocery store everytime you need something, think how much time,
gas, and energy you waste.
I usually get my groceries in one store
close to my work on my way home on bike, so I don't need to go back
there again until another week or even month. I get my other needs from
the other store on my walk way to meet my friend. Combining (all possible) tasks within the same route makes everything simpler.
