Excerpt from "Cast away" written by William Broyles Jr.
(Chuck Noland, after his plane crash and his living alone on a island for about 4 years, is finally rescued and returns home.)

Chuck Noland: We'd both had done the math. Kelly added it all up, she knew she had to let me go. I added it up - knew that I'd lost her. 'Cause I was never gonna get off that island. I was going to die there, totally alone. I mean, I was going to get sick or injured or something. The only choice I had, the only thing I could control was when and how and where it was going to happen. So I made a rope and I went to the summit to hang myself. I had to test it, you know, of course, you know me. And the weight of the log snapped the limb of the tree. So I - I couldn't even kill myself the way I wanted to, I had power over nothing. That's when this feeling came over me like a warm blanket. I knew, somehow, that I had to stay alive, somehow. I had to keep breathing, even though there was no reason to hope. And all my logic said that I would never see this place again. So that's what I did. I stayed alive, I kept breathing and one day that logic was proven all wrong, because the tide came in gave me a sail. So now here I am. I'm back, in Memphis, talking to you. I have ice in my glass, and I've lost her all over again. I'm so sad that I don't have Kelly, and I'm so grateful that she was with me on that island, and I know what I have to do now. I gotta keep breathing, because tomorrow the sun will rise, and who knows what the tide could bring?

Every person,at some moment of his life, is like Chuck Noland...alone and helpless on an island. He may be among crowds but still feels alienated.
The duration here depends on your tide or rephrased your destiney.
Your destiney here depends on you or rephrased your dealing with it.
Most of us lose hope too soon. We hang ourselves without testing, so we don't die but we break a leg or get injured achieving the exact contrary of what we wanted, ending our problems for good, and instead we increase our pain even more.
What's ironic is that it always happened right before the tide comes.If we only had been patient!If we only had had faith!
One once said:"If you're going through hell...keep going."
Everything has its start but also its end. On the way we'll lose things, precious things, like kelly, but that's how it goes, you gotta keep breathing coz u nver know what the tide may bring.

Life is game.
