How to tolerate ambiguity?

From reading some articles online regarding the psychological concept of "ambiguity tolerance" I have learned something brilliant. I have a low tolerance for ambiguity and that has been crippling my life for years, academically as well in terms of personal development, my intolerance of ambiguity has caused me huge problems in life.
Do any of you know of any literature detailing ways to become more tolerant of it? Ways to become more comfortable with it? Please help!
