After reading this book, what immediate improvements do you feel you need to make in setting personal boundaries?

Here is the English translation in Markdown format:

After finishing this book, it felt like I was woken up by a slap across the face. There really are several things I need to change immediately, and they all cut deep—because I realized how often I've lived in a complete daze before.

1. Stop Over-Explaining My "No"

I realized I had this huge flaw before: whenever I refused someone, even for the most trifling matters, I'd instinctively churn out a million reasons and invent perfect excuses, terrified they'd be upset.

• Me Before: “Oh, I'm so sorry, I probably can't make it Saturday. I think I have something scheduled that morning, then my mom wants me home for dinner in the afternoon, and I might have to work late… plus I've been feeling pretty tired lately…"

• The Problem: The more I explained, the more I handed over the "right to debate." They could argue against every single point: "Couldn't you reschedule your morning thing?", "Couldn't you sneak out from dinner early?", "How late is this overtime…?" In the end, I'd get talked in circles, feeling guilty or genuinely wrong for saying no.

• Change Now: Say "no" directly, kindly, but firmly.

  “Thanks for the invite, but I won't be able to make it this time.” “I won't be able to help with that, I'm afraid.”

  That's it. No elaborate explanations. The book taught me a core truth: Healthy people respect your "no," while those trying to control you demand your "why." I don't need to justify my refusal to anyone. My time, energy, and feelings are mine to manage.

2. My Feelings Don't Require Anyone's "Approval"

Before, if something made me uncomfortable and someone said "You're overthinking" or "You're too sensitive," my first reaction was self-doubt: "Am I really overthinking? Did I blow it out of proportion?"

• The Problem: My genuine feelings were easily dismissed. Gradually, I even stopped trusting my own intuition and judgment. This opened the door to emotional manipulation (PUA).

• Change Now: Treat my feelings as "facts," not "opinions". If someone cracks a joke that makes me uncomfortable, I'll say: "That joke makes me really uncomfortable." If they reply: "It's just a joke, lighten up!" I won't doubt myself. I'll stand firm:

  “This isn't about sensitivity. The fact is, it made me uncomfortable. Please don't make jokes like that with me in the future.”

  My feelings are my feelings. They don't need your permission or approval. What doesn't bother you is your business; what disturbs me is mine. I must defend the legitimacy of my feelings 100%.

3. Establish "Offline unless Necessary" Digital Boundaries

My phone used to be on 24/7 standby. No matter who messaged or when, I felt pressured to respond instantly. Especially with work stuff—if I saw it late at night, I had to deal with it.

• The Problem: My personal time was shattered. My mind was always in a tense state of alertness, never truly relaxed. This silently told everyone: "My time is worthless; disturb me whenever."

• Change Now: Hang a "closed" sign, both offline and online.

  • After work, mute notifications for work groups. Unless it's the end of the world, handle it the next workday.
  • Enable Do Not Disturb after 10 PM. Family can break through for emergencies, but ignore all other messages and notifications.
  • Stop trying to reply instantly. When I see a message, if it's not urgent, tell myself: "I'll reply after I'm done with what I'm doing."

  I need to reclaim control of my life. I'm a human being, not a 24/7 customer service bot.

To Sum It Up

Overall, the biggest shift is moving from an unconscious rule of "making others comfortable first," to making "my own comfort and well-being the priority." This isn't selfishness; it's self-respect. Boundaries are like our body's immune system. Before, mine was essentially broken down. Now, I'm rebuilding it, making it strong again, little by little through these everyday acts.
