If you look at life as a tape measure, it puts things into perspective.
One year equals a foot. One month equals one inch. Stretch that thing out to 80 feet or so and you’ve got a very very very long life.
A bad day? That’s one 30th of an inch. Hardly noticeable. Barely visible. Now, compare that one bad day to all of history. It can’t be seen. Compare it to all of eternity, and it’s as if that bad doesn’t exist at all.
Yesterday might’ve been a bad day, but it’s gone and doesn’t matter. Today we can turn things around and focus on the positive we can make of our lives for the rest of eternity.
