You can only fall so far through a tree before the limbs become abrasive to your body.
This quote metaphorically illustrates that setbacks and challenges have their limits. Just like falling through a tree, there is only so much one can endure before the obstacles start causing discomfort or harm. It serves as a reminder to recognize personal boundaries and avoid pushing oneself into situations where the difficulty becomes counterproductive. Embracing this awareness can help with pacing, resilience, and choosing when to step back or push forward.
