It's easy to live as if there's an endless supply of days — to treat this one as a rough draft, a thing to get through on the way to the real life that starts later. There is no later that isn't also made of days like this one.
This isn't meant to frighten. It's meant to wake. The ordinary Tuesday you're half-living is, in fact, your one life happening. The people in it are here now, not forever. The deferral is the trap.
You can't make the day longer. You can be more here for the one you're in — which is, in the end, the only thing that turns time into a life.
