Break free from your deep-seated lack of confidence.

When visiting relatives, seeing them busy moving things around, you stand on the side feeling helpless and unsure of what to do. But in your own home, when you see someone carrying things or busy working, you naturally join in.
Getting into an interview through a written test, your name is on the list. No matter who the interviewer is, you have to sit and speak for fifteen minutes. This space should have a part of you, and the air also contains a part of you.
Have you noticed something? What you want is not confidence, but this feeling.
Many people lack confidence because subconsciously they see themselves as visitors entering someone else's space, rather than as a rightful co-user of that space and environment. From the very beginning, they have "self-objectified," believing they lack a "sense of the protagonist" and a "deservingness."
Why do you feel relaxed in front of friends? Why are you never insecure in front of family? The fundamental reason is that you default to having a share in that space. But in work settings, in front of leaders and strangers, the default shifts, switching to visitor mode.
All your attention is focused on observing others' words and actions, unconsciously adhering to rules that only exist in your imagination. Overly concerned with others' opinions, anxious about how others see you, afraid of making a bad impression—at the root, it’s a lack of self-acceptance.
True confidence doesn’t come from learning tricks. Developing functional skills is very difficult; these are superficial "techniques," external moves that are hard to sustain long-term. What’s needed is a "Tao" level, internal mastery: learning to default to the idea that this space has a part of you in any situation.
As long as you stand here, as long as you appear in this setting, this space will have a place for you. Don’t see yourself as a guest; you’re not here to be judged or evaluated. Don’t constantly see yourself as an outsider—allow yourself to exist. You don’t need others’ permission to be yourself.
