It is important to know our good and bad points because this knowledge will help us to improve.We should examine ourselves and learn who we are.Above all,we should recognize our strengths and weaknesses.For example,I am healthy and fit,so I can work hard.I'm also optimistic,humble and polite.These are my strengths.However,I also have weakneaaes.For one thing,I'm stubborn and a little impatient.I'm sometimes lazy as well and can spent a whole day just watching TV and eating junk food.I'm not ashamed to admit these bad pints.Knowing what they are lets me focus on improving myself.
