Security is mostly a superstition. It does not exist in nature, nor do children as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure, or it is nothing. Don't let yourself indulge in vain wishes.
Adventure is by normal definition, an unusual or exciting experience.
What may be one person's adventure is another's humdrum existence. Most would agree, for example, that thrashing through a jungle with a machete to escape a charging rhinosaurous would fall into the 'adventurous outing' category. Adventure, it seems, lurks closer than we realize. We've all heard stories, too, about someone happening upon some little adventure, simply by taking a wrong turn, or being in the wrong place at the wrong time. Whether an accident or a missed opportunity, we'll never know how closely we came to having our lives changed forever.
