It's difficult to defeat the overwhelming feeling of "There is no future (Or at least not a good one), so what's the point?". I feel like even if I live to 100 we're not going to be anywhere close to a Star Trek utopia, but more smack dab in the middle of a Dark Age.
Y'know why it's a tragedy when an olive grove is destroyed? Because they do not grow in a lifetime. Olive groves are a gift from those before to those after. We were not the first to sow, but we are also not the last. When you find rare fruit, share it, and one day, it may be reaped in abundance.
