One obstacle to feeling this peace is perfectionism, disguised in "shoulds." Here are a few key ones, listed in the The Anxiety and Phobia Workbook:
"I should always be pleasing and cheerful to others, despite my feelings.
I should be totally competent.
I should be the perfect spouse, parent, lover, friend, worker, student . . .
I should be totally self-reliant.
I should never get tired or sick.
I should never feel negative emotions like anger or jealousy.
I should have achievements . . .
I should never be afraid.
Today, loosen up your constricting shoulds. Feel yourself exhale. In that space is more room to feel Love's unconditional appreciation of you. More room for creativity and intuition and surprise and good humor and proper perspective.
