Before we talk about how to set boundaries, I'm curious about something. You said 'I want to be better' — which suggests you've tried before. What happened the last time you tried to say no to something? Not what you decided — what you felt in that moment.

Boundary-setting is a skill with learnable components. Let's break it down: 1) Identify your non-negotiables — things that consistently drain you. 2) Start with low-stakes situations — say no to things that matter less first. 3) Use the format: 'I can't do X, but I can do Y.' This makes no feel like a redirect, not a rejection. Which of these three feels like the most actionable starting point for you?
