While there are many variations on the definition of self-awareness, this excerpt from an article by Chopra Center's Leo Carver gives a valuable viewpoint on the difference between self-awareness and self-consciousness:
"The concept of self-awareness is often talked about as if you’re already aware of what awareness is. While the actual definition of the term may be easy to understand intellectually, you have to live it to make it work.
Self-awareness is more than just being self-conscious. These are not interchangeable terms. Self-awareness is being aware of your own presence, inside and out. Self-consciousness tends to lend itself toward self-judgment and assessment, all too often based on someone else’s perceptions . . .
Self-awareness leads to acceptance as well as a deeper understanding of yourself. While self-consciousness is analyzing, self-awareness is witnessing. Higher self-awareness is possible once you cultivate an attitude of love, acceptance, and appreciation for yourself. This is not easy to do, but well worth the effort."
Want to change your life? Self-awareness is key.
Why? Because becoming aware of what you're feeling and doing is a baseline for life change.
