(This is stream-of-thought, non-sensical rambling. I held back from deleting this entry because there might be something here worth eventual contemplation.)
As kids, we look up to others and are compelled to grow. What is there to look up to as an adult? Do we not stop growing and eventually die? What if we kept looking up? Would we keep growing. Figuratively, I mean. Obviously, because we wouldn’t really want to eternally grow physically, that’d be stupid. Although constant renewal and perpetual maintenance of good health, if balanced, would be an enticing example of perpetual growth.
We also don’t hold back on our passions when we are younger. This unbridled enthusiasm could also be a source of vitality.
