Admittedly, ambiguity might be one of the hardest things I face in life. Part of the challenge is that ambiguity is a constant; it will never cease to be a fundamental element of life.
I work to allow ambiguity by reminding myself that it is impossible to control all aspects of my life and it's only the childish parts within me that aim to do so. I reassure myself that, invariably, life has always had a wilder imagination than I ever have so relinquish expectations for only the outcomes I can fathom.
When we let go of control, when we let go of expecting certain outcomes, when we succumb to the inevitable ambiguity of life, life becomes that much more exciting AND delicious.
