5. Reveal your flaws.
No one is perfect, so there is no reason to act like you are. People who aren’t sure of themselves tend to ignore their flaws. Don’t be afraid of making mistakes if you don’t want to look like you’re not sure of yourself.
People who talk about their flaws are thought to be more honest, which is a sign of self-confidence. Also, people will like and be drawn to you more because they won’t see you as a threat and will be able to relate to you.
