Your past experience influences your present. And your present will inevitable influence your future. Learn from your past and make the right conclusions as well as wise decisions.
If you consider yourself a mature individual, you are supposed to know the following:
You live once. And you deserve to be respected by other. Do not let anyone put you in frames, dictate what you should not do or limit your opportunities. You might not want to try to fit into anyone’s tiny box. Be loyal to your true self.
You are no longer a peacemaker. Maybe in the past you tried your best to be perfect. However, there will always someone who dislikes you or disagrees with your attitude and behavior. Give that habit up and enjoy your individuality.
