Conviction is meant to redirect your path. It is not to judge you nor hurt you. Just because you are "grown" does not mean that you do not need to improve the way you think or react in situations. There is always room for improvement in your life. When you are 18, you think you know everything you need. Alot of us refuse to listen to people who are older than us. This is a mistake! Some people go through things in life, so we will not have to. I personally would give advice to someone in order to prevent them from getting hurt or making a mistake. You are never too old to learn and improve!
