I know not to absorb “mung” from spewers of negativity and unhappiness. Still, caustic salvos sometimes slime their way into my brain, squelching my imagination, confidence, and optimism. When I reflect, I realize the vile intruders have access only if I permit them.

Thankfully, the duration of most naysayers' and dream slayers' trespass is usually short-lived. My senses’ defenses often thwart the negative vibes and barbs. Occasionally, though, the constant dirge of you cannot and you should not erode, and eventually breach, the walls of my sunniest outlook.

Self-imposed exile is one answer--escape and distance for sanity’s sake. My alternate, preferred defense is to choose determination over despair.

Reflecting, I realize the impetus for many of the greatest triumphs in my life are linked to others' doubts or dares. Skepticism or goading spurs me to marshal resolve from my head, heart, gut, and toes. Anyone’s assertion that I cannot or should not do this or that becomes a challenge. To me, being determined is a compliment, not an impediment.

In case my memory wanes, I display this Chinese proverb nearby: "Those who say it cannot be done should not interrupt the person doing it."
