Rather than 'giving up' something, I'm trying to add something. I'm doing a good turn every day, which is something unexpected and lovely.
For example, on Saturday I was in a bookshop and picked up a book to buy, at the same moment a mum and her daughter came along with the daughter sounding all excited about this particular book. I realised it was the one I was about to purchase, so handed it over to her. It made my day!
I've also so far surprised my mum with a bunch of flowers, sent text messages to my friends to say how much they mean to me, secretly bought people an ice-cream, letting people out in front of me in the traffic, and just little things to make people smile and maybe then they'll pass the good feeling on!!
