Navigating an invisible tightrope is challenging.
Let's imagine there's a tightrope that you need to carefully balance on as you walk.
That's challenging in the best of times.
But imagine if it's also invisible.
Often, and without warning, you take a step and fall to your death.
It takes tons of very expensive and painful trial and error to figure out where the tightrope is.
When you make the wrong step, you don't realize until you go tumbling.
A few ways to make it easier:
1) Make it visible, so you can see when your step is about to cause you to tumble.
2) Put up alarm bells so if you make a mistake, before you commit to it, you get a proactive warning.
Another challenging situation: when you can see the invisible tightrope but your friends can't.
They'll come over and jostle you and say "why are you being so serious and slow" and accidentally put you in danger.
