Or, in other words, what does it mean to be insecure about something?
If you think about it, there is no universal definition for what being insecure means, but it likely means you’re either unhappy or unsure about some aspect of yourself.
Being unhappy (which means you’re experiencing a negative emotion/feel bad) means you’ve gone beyond disliking something about yourself to viewing what you dislike as a reason to feel bad about yourself. You’re probably unconsciously doing this.
In other cases, being insecure means you view other people disliking some aspect of yourself as a reason to feel bad.
When you’re not sure of something.
What about the moments when you aren’t sure you’re something you want, like being attractive or smart? This becomes an insecurity if you are or would be unhappy if you or others didn’t think you were the ideal you’re striving for. If you are able to accept not being something ideal–which doesn’t mean you don’t dislike that fact–you have overcome your insecurity.
You don’t have to be insecure about anything because you don’t have to feel bad whenever you dislike things.
