The essence of mental flexibility is the ability to handle different situations in different ways, especially to respond effectively to new, complex, and problematic situations. The mentally flexible person is able to:
-see things from several different perspectives
-tolerate ambiguity and uncertainty
-take risks willingly
-adapt to change
-learn from mistakes
-solve problems in new ways
-switch between practical and non-practical thinking.
