The literal meaning of life is whatever you're doing that prevents you from killing yourself.

If nothing had any meaning, you would be right. But there is something that still has a meaning.

This heart within me I can feel, and I judge that it exists. This world I can touch, and I likewise judge that it exists. There ends all my knowledge, and the rest is construction. (...) Forever I shall be a stranger to myself.

How did I picture the life after the grave?

I Fairly bawled out at him: 'A life in which I can remember this life on earth. That's all I want of it.

You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.

After awhile you could get used to anything.
