Falling in love, romance, matters of the heart - when you fall in love, on some biochemical level you know there is a chance it won't work out. It's ingrained in us that if you take such an enormous risk on someone with your heart that it might not pay off. I gamble all my chips and I might actually lose everything.
The earth is such a voluminous, sparse, wild place that has its own rhythm that human beings try to control and strategize our way around, but the truth is, if you're out someplace like the ocean on a capsized boat, it doesn't matter if you have academic degrees, or if you're a martial-arts ninja. Nature is a bigger force than you.
