I can do something similar: unconsciously, I don't hope too much, in fear that my hope will attract its opposite. I don't express too much delight in a positive experience for fear that I am setting myself up for disappointment in the future.
Today, be open to accepting goodness in its fullness. Know that accepting goodness does not make you weak and unable to bear future disappointment or discouragement. It actually strengthens your courage and sense of possibility.
Love gives you the ability to do this.
