“ I am longing to be with you, and by the sea, where we can talk together freely and build our castles in the air. ”
If you can love someone with your whole heart, even one person, then there's salvation in life. Even if you can't get together with that person.
If we will be quiet and ready enough, we shall find compensation in every disappointment.
The very least you can do in your life is figure out what you hope for. And the most you can do is live inside that hope. Not admire it from a distance but live right in it, under its roof.
At what point do you give up - decide enough is enough? There is only one answer really. Never.
