Change?

Life's full of change.
Good or bad, we're rearranged.
Sometimes we're bigger.
Other times we're poorer.
But no one says we're wiser.
No one says we're smarter.
Yet we learn so much more.
More of what life is for.
And we don't see that fact.
Instead we still say we lack.
So what is it in life.
That make us all strive?
