In life, some things should always be remembered, others are best to forget. It is wisdom to know what to remember and what to forget. Remember what should be remembered, and forget what should be forgotten, yours. Life will be happy and peaceful; on the contrary, if you don't forget the thoughts you should forget, and you can't remember the things you should remember, then your life will be overcast. Through this passage, the author tells us that life is alive, should it? ['Remember things that are always worth remembering.', 'Remember what should be remembered, and forget what should be forgotten.', 'Forget those clouded things as soon as possible.', 'Correct distinction between what should be remembered and what should be forgotten.']
