But doesn't that happen to everyone at one stage or another? Don't we all crash at sometime? We learn from the experience and move on.
The point is, do you want to look back on your life and think to yourself "I've accomplished X. But looking back, what have I missed?" One of the Four Noble Truths in Buddhism is that the cause of suffering in life comes from the desire to have and control things, such as one's own life. The real problem there is that you can't control life, the same way that you can't tell what will happen around the next bend, or what's coming.
I said earlier that my grandfather was on the last sailing ship built in the English isles, the Kathleen and May, a schooner. He signed on as one of the crew when he was 16, and spent two years sailing on her before the diesel fumes from the engines caused him to develop a severe ulcer (it would later require much of his stomach to be removed), and so when he was 18, as the Kathleen and May sailed into Cardiff, he was allowed to leave. There he apprenticed as a brick-layer and he met my grandmother, and began to buy old houses, fix them up, sell them and move on. Eventually he got a job with a large steel mill as one of the supervisors, simply because one of his old brickie mates knew some of the managers. Working there, he was able to build a home for his family, and he was able to retire in some comfort. My grandmother passed away when I was 13, from leukemia, and it was a harsh blow for him. He developed cancer when I was 15, and that required his left lung to be removed. He passed away one month short of my 18th birthday, from a reoccurance of the cancer.
A year before he died, he came over for a visit and in one of the few meaningful chats we ever had, he told me that life had dealt him some terrible blows, but had also shown him a great deal of kindness, he had been able to see he grandchildren grow up, and was able to meet his great grandson. He even admitted himself to be a simple man, no lofty ideals, no grand scheme in life. He was just a boy who signed onto a ship who didn't care what was on the horizon, only that there must have been something there.
