Maybe under-appreciated?
Living in the land of plenty, in the land of the over-stuffed, the hyper-caffeinated, the constantly morphing & roiling hurly-burly, the belly of the beast, always-on, overwhelming, 24/7 megalopolis of cheap thrills, easy distractions, sexy come-ons...
... it is so easy to lose our minds. To give up our space to the crowd.
Mental space is a precious commodity. I mean, it's not even a commodity. You can't buy it. You can only cultivate it, grow it like a garden, it's a living thing, invisible, inside of you. A sacred space, a secret garden, a safe place of contemplation, silence, deep breathing.
Without discipline, without a practice, you are toast. Invaders from all sides. If you don't learn to protect your inner space, everything can come crashing in. Best to practice. To decide what you won't do, where you won't go, what you won't listen to, or watch, or take in at all.
Sometimes less really, really is more...
