I have to disagree here. After being faced with the difficult truth of life's fragility, I feel like people and situations are fleeting. Everything is temporary. But I think love is a renewable energy source, so to speak. People die, but I think their love for us will last forever. We'll take with us memories, images, etc. and feel that love again (eventually.)
Dreams are the only thing that can remain constant for me. When my world came crashing around me, and I didn't have dreams, or a goal or sense of purpose, I just felt like I was falling in a neverending well. But my dream is really all I can cling to right now, and lately it is what gets me through the day.
Love to me is something that comes and goes, that changes, and that more than any other emotion is completely unreliable. I no longer trust it.
As for dreams, I have no dreams any more. Goals, yes, but dreams, certainly not. They are too divorced from reality for me and are never fulfilled.
