21 Days of Healthy Boundaries

The phrase "21 Days change causes Healthy Boundaries" refers to the idea that by dedicating 21 days to actively practicing setting boundaries in your life, you can significantly improve your ability to establish and maintain healthy boundaries in your relationships, essentially forming a new habit of prioritizing your needs and communicating them effectively within a relatively short time frame.

Key points about this concept:

• "21-Day Rule":
  While not scientifically proven to be a magic number, the "21-day rule" is a popular concept suggesting that consistent practice over 21 days can help solidify a new habit. 
• Focus on Practice:
  The key aspect is actively practicing boundary setting in various situations throughout the 21 days, not just passively thinking about it. 
• Benefits of Healthy Boundaries:
  Setting clear boundaries allows you to protect your emotional well-being, prevent resentment, and foster healthier relationships by clearly communicating your needs and limits. 

Where this concept is often used:

• Self-help programs:
  Many personal development programs incorporate a "21-day challenge" focused on building healthy boundaries, often providing daily exercises or prompts to guide practice. 
• "21 Days to Better Boundaries" book:
  This book by Ann Weiser Cornell specifically focuses on a 21-day practice to develop effective boundary setting skills with kindness and compassion. ​

What is the psychology behind setting boundaries?
Many people feel inclined to justify their boundary—to offer a “why” and provide a rationalization or even apologize for the boundary. But the very purpose of the boundary is self-preservation—setting a limit to protect one's mental health and well-being. This is something that doesn't need to be justified.
