" God, grant me the serenity to accept the things I cannot change,
Courage to change the things I can,
And wisdom to know the difference. "

I do the serenity prayer more often than negative visualization. It has definitely changed my perception of things, especially in times of frustration. I still complain internally when frustrated but am more accepting of these events that are beyond my control. The events are beyond my control but how I perceive these events are. :)
