So many self-help ideas are like meringue - you take a big bite, and there's nothing there.

What I've learned is there's a scientifically proven phenomenon that's attached to gratitude, and that if you consciously take note of what is good in your life, quantifiable benefits happen.

If I have time to exercise, I do it, but I don't fixate on numbers like weight or waist size. Numbers don't work for me.

I'm about as straight an arrow as you'll find out there.

'Thank you power' is writing down the moments that are good in your life so that you can go back and reflect on them - so you've got this sort of repository of good stuff in your past.

There is a comfort in rituals, and rituals provide a framework for stability when you are trying to find answers.
