It's never good when the earth moves. Earthquakes never build, they only destroy. When what you rely on to hold you up, when the very thing that supports you quivers and gives way, then all that you have built collapses. This is true of buildings that rise from the ground, and it is true of our lives as well. To be "all shook up" is to be upset, confused, and unsure of what to do next. Traumatic events can leave you "badly shaken," not knowing what to expect or how to react. Our plans can be shaken. Our foundations, be they emotional, financial, or professional, can crumble away.
