We were not born to be timid. Wary, cautious, sure, depending on the situation--our survival depended on it. But here's the thing--wariness, cautiousness can make us stronger. They can make us braver. They are the first tools we need when we go out into the world, because to feel cautious, to feel vigilant means we are testing ourselves, stretching ourselves, exploring the world--either literally or creatively--we've been set down upon.
But to let timidity creep in, to let it keep us from stepping outside our front doors, is a terrible loss. Timidity is a taker of hostages and if we don't rise up and fight back, then we'll be doomed to the same uninspired view for a very long time.
