'A guiding star in a world filled with infinite choices' - Emma Reed Turrell

The gentle guide to getting where you want to go, without beating yourself up on the way there.

I'll never eat sugar again!
I’ll work out every single morning!
I will never, ever shout at my kids!

Sound familiar? Anna Mathur, Sunday Times bestselling author and psychotherapist, has been there too. In The Good Decision Diary, Anna introduces a compassionate and realistic alternative to unsustainable promises. This isn’t about perfection - it’s about progress.

The journey begins with 21 days of reflection and observation, where Anna shares her own experiences and equips you with tools to approach change with kindness and curiosity.

From there, she gently guides you through a 14-day practice of questioning behaviours, challenging long-held beliefs about change, and identifying patterns of self-sabotage. You’ll discover how a decision that nurtures you one day can hinder you the next - and how to tell the difference in the moment.

The Good Decision Diary will help you make better decisions, not all of the time, but more of the time.
