As early as 1997, Christian Lindner, now Germany's Minister of Finance, knew that crises and problems are "also just thorny opportunities. What at the time seemed more like a rhetorical, flowery battle cry from a brash young entrepreneur is, in essence, still a resilient, psychological fact today. Shocking strokes of fate or other drastic experiences often literally pull the rug out from under people - and change their perspective on their own lives. However, this forced change of perspective can also be a real opportunity for change for the better, if one has learned to deal with crises and to recognize and seize the opportunities hidden in them.
