On impulse at a train station I once bought Your Best Year Yet by Jennie Ditlzer, and a friend and I had fun and got very motivated by working through it together. I passed it on many years ago but have just re-ordered it.
Although I don't expect to have the same experience from it I still like the ten questions Jennie Ditlzer asks. (You can see them in the preview on Amazon to see if it might be useful to you too.)
As many of you will know, after a bereavement or other loss it is a common thing to lose confidence in yourself. The first question in the book is What did I accomplish?
I found a new notebook and began to list the things I have achieved since Barry died - beyond getting up in the morning, eating and sleeping, and dealing with absolute essentials - which some days felt like big accomplishments in themselves.
Light bulbs flashed!
