Saying 'Yes' is easy. Carrie talks about what happens when we mix up 'Yes' and 'No' between what we say and what we do. It's a good read.

She includes four exercises:

1. Say No when you mean No at least 3 times a day all week and stick to it.
2. Pause before you say Yes and make sure you mean it.
3. Notice when you say No, but do Yes and get curious about what is going on.
4. Notice when you say Yes, but do No and get curious about what is going on.

Easy to do. Hard to internalise.
