Simeon, after seeing Baby Jesus at his presentation to the Lord at the temple, was ready to die in peace. For the Holy Spirit had revealed to him that he should not see death before he had seen the Messiah of the Lord. Am I ready to go in peace too? Yes, because although I have not seen Jesus, I have gotten to know him so well that seeing him is not going to help me believe in him more. Besides, there's nothing left in the world worthy pursuing anymore. If Jesus is not ready for me to go because his work for me is not yet complete, that would be fine too. The important thing is that we be ready for him.
