I just found this, since we're talking about healthy boundaries:

What are healthy boundaries?

1. Saying no without guilt
2. Asking for what you want and need
3. Taking care of yourself
4. Doing things out of interest/desire, not out of obligation or to please others
5. Behaving according to your own values and beliefs
6. Feeling safe to express difficult emotions and have disagreements
7. Pursuing your own goals
8. Taking responsibility for your own happiness
9. Not feeling responsible for someone else’s happiness
10. Being in tune with your own feelings
11. Knowing who you are, what you believe, what you like
