Pretty much he's saying not to go with the flow, "Strove against the stream" and to be yourself. But at the same time, this world and society is so based on "fitting in" it's making him want to "escape to the stars" to find relief from this world. He wants to do what he wants and be free with the woman he loves. One he escape to the starts and he can be himself with the woman he loves, he'll be free from "reality" and start a new life.
