We need adventure for our waking hours every bit as much as we need security for our sleeping ones. When you have had both, you generally know it, looking back, even if you were completely unaware of it at the time.
All it takes are some new surroundings, and active imagination, and time to explore – things we never stop needing to have. Most of the people I know whose lives have little-to-no adventure have surroundings and time, just little surplus imagination. They’ve frequently abandoned their imaginations somewhere on the road to adulthood, feeling them to be childish things best discarded. This is a mistake, of course; without imagination, there can be no empathy, and without empathy, you have — well, you have much of what we have too much of in the world right now.
So explore a little. Open a few doors. Go down a few new roads. Remember what it was like when possibilities were at least as big as our realities. That is a feeling we can recapture, if we’re open to it.
