This quote, by Soren Kierkegaard, explains that life is best understood backwards–in hindsight. But the trouble is that we must live it forward. We must live it in that unsettling space that falls between a confounding present and an uncertain future. As such, we often don’t understand why things are happening as they’re happening.
It helps to remember that it’s usually only when we look back after some time has passed that things begin to make sense. So be patient as the puzzle pieces appear to fall randomly with no connection to each other and trust that you’ll eventually begin to see the full picture.
