While I think gardens are wonderful in any form......from plowing a field, to a few pots on the patio, or a few herbs on the window sill, I will stop short of saying " everyone should".
There is enough burden to modern day life already. I will not tell my neighbor what he or she "should" do. If they wish to attempt gardening, I will be in their corner, doing all I can do to help, just as they allow me to.
It is very discouraging to see your first attempts or crop fail~~
