"Remind yourself that it's okay not to be perfect"
Always remember that nothing in this world is perfect. And you as a person are not obliged to be one. For learning is all about making mistakes. You find your purpose through it. And life is an ongoing process of learning and correcting errors. No one in this world is created faultless. The only varying point is that some learn from their mistakes in order to be perfect. Others continuously make mistakes and never learn from it. Allow yourself to be judged and corrected, for through it you become a better person.
Remember that being perfect is only a dream that is unattainable. Despite that, aspiring to become a better and knowledgeable person is more realistic. All you have to do is to accept imperfections.
