It's a more narrative word for "pivot" or "transition."
Everything works in cycles. We all go through phases.
Life is much simpler when we appreciate the rides we are taken on. When you experience a string fortunate events, enjoy every moment of it. Even during the inverse of that, the best you can do is keep your head up and realize another wave is on its way.
We can sit back and be victims of circumstances or we can get out there, be aware of our own situations, and position ourselves optimally.
Regardless of how you respond, expect the cycle to continue in perpetuity. That's what makes it so much fun.
