growth ring

It something like your past experiences that you survived. Maybe it is an another term for adulting and being aware that you're getting old. Just like a tree every year we have a different version of our selves.. and if you cut a tree you'll see the layers it is called growth ring.. we'll for it's just like human too.
This just prove that we are not develop yet but it doesn't mean we can't get better.
And the growth ring will help us to grow and be better version of our selves.

My growth ring is slightly visible now.
