When you're in hot water, imagine how much worse it could have been. Then you'd realize you're actually pretty lucky, because those things that could have made your days a lot worse did not happen. There are no worst situations, only worse situations.
It can get better or worse. No party will last forever, whether it's a good party or bad party.
I believe how things turn out is based on our effort AND fate. A good analogy is we're like fish in the river. We can swim around at our will, but meanwhile the water flow carries us with it. When we approach a waterfall, no matter how hard we swim, we might still get flushed down. Now there're certain fish species that swim against the direction of water flow to get to their breeding grounds, but when the flow is strong enough, there's nothing they can do. I suggest you try your best, and leave the rest to fate.
Sometimes it take a little twist in your mindset to come to more peace with yourself.
