Do you believe in this -“ Whatever flows, flows; what goes goes”?

I’m learning to be detached and just trust the flow of life and universe to bring whoever and whichever experience into my life it deems appropriate; and trust that whatever leaves has probably passed it’s expiration date in my life. Do you believe in this outlook on life as well or do you have a different perspective?
