Suggestion for an exercise in humility, contentment, and gratitude for what you have:

Near closing time, go down to your local, largest bulk supermarket to do your shopping – Asda, Tesco, Sainsburys, Wal-mart, whatever…

Look, be aware of and take notice of what everyone else has in their baskets at the checkout.

Repeat occasionally at varying times of day for several months.

Think, very very hard.
