Nothing in nature grows forever. It grows, then it thrives for a long time when it reaches its natural limits (creating its own comfort zone), then it eventually dies.
For natural things, what is key is to learn the awareness of when to stop growing and when to thrive alongside and with the other natural things around you. And to maintain that state of beauty within you and around you for as long as possible.
Endless growth is unnatural. Except. The only thing in the natural world that grows endlessly without stopping is……cancer. And that kills quick.
Growth without balance (without at some point stopping, resting, and enjoying what you are and have become) hastens death.
