Boundaries aren't about being selfish—they're about being sustainable. Consider:
Without Boundaries: - You help poorly due to exhaustion - You resent those you're helping - You burn out and help no one - You model unsustainable behavior
With Boundaries: - You help excellently when you choose to - You maintain positive relationships - You sustain high performance - You model healthy professionalism
The question isn't "Am I being helpful?" It's "Am I being helpful in a way that I can sustain and that truly serves others?"
