For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly trustworthy physical and human environment. But when the expected course of everyday life is interrupted, we are like shipwrecked people on a miserable plank in the open sea, having forgotten where they came from and not knowing whether they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment. - Albert Einstein
