It struck me during Tough Mudder that monkey bars are a good metaphor for life. In order to move forward, we have to let go.
I observed several people who were too scared of letting go and falling that they weren’t willing to let go when the time was right. Their fears were realized as they fell to the pit of muddy water below. Had they held on only just enough and let go at the right time, they might have made it across. In order to move forward, we have to let go.
