Hi @Lizel! Yes, I think the lack of confidence to oneself is one of the major cause of wanting to look good on the outside. It's not a bad thing to want to look good so you would look pleasant in other people's eyes, but when a person already becomes so obsessed in wanting to impress others it will no longer be healthy. If we get so consumed by wanting others to see us as physically beautiful and perfect, that's when the problem starts. As what @harold has said, no matter how many times we undergo changes in our physical selves if we don't get contented, we will never stop. Contentment to oneself and to what has been given to you is the key to real happiness and acceptance of yourself. We should not focus on wanting to impress others because their views are not the most important. Your own view about your own self is the most important view of all. As long we see our true beauty, which is never really physical, it will brightly radiate outside for others to see and appreciate. Let's try to look for the beauty we have from within first, and our natural beauty will exude.
