We all have our insecurities. Nobody is perfect. We constantly wish we had better things, better features, better body parts, and so forth. But life need not to be perfect for people to be happy about themselves.
Self-improvement and loving yourself isn’t a matter of crying out to the whole world that you’re perfect and you’re the best. It’s the virtue of acceptance and contentment. Once we begin to better ourselves, we then are able to be convincing in a conversation with prospects.
