I have been in fog and also have had my head above the clouds; both literally and figuratively. Figuratively speaking, being in the fog or having head in the clouds both don't help.
Having unrealistic goals or being confused both have negative effects. Sometimes, and quite rarely, the ideal world above the clouds can seem very beautiful but it is not achievable.
Thanks for your interesting viewpoint and experience!
Of course derived from your article so thanks for writing.
