Be an independent person, never blame others for not helping you, and never blame others for not caring about you. Living in the world, we are all independent individuals, and we all have to suffer pain and discomfort. On the road of life, we are all lonely walkers. For example, if you drink water, you will know yourself well. Don't wait until you are hurt, and don't wait until you are sleepy. The only person who can really help you is yourself forever.
