When you feel the weight of your situation bearing down on your shoulders, try to make a list of at least three things you usually have fun doing and tape it to the fridge or a kitchen cupboard that you see regularly.
The list can contain anything from knitting, ice skating, bathing and grooming the dog, star gazing, giving yourself a pedicure, meditating or visiting an art gallery; the only pre-requisite to be on the list is that the activity should give you pleasure. Decorate it with silly smiley faces too, you don’t have to be van Gogh about it, an L S Lowry stick-woman will do.
If you see the list enough times as you pass through the house, eventually you’ll seduce yourself into doing one of them and hopefully restoring your smile again.
It only takes one happy event, one positive occurrence to happen and you can wipe out a whole tide of sadness in one motion. It might not last forever, but it’ll set the tone for a happier day.
