... will always hide the bad stuff.
It's still there though.
You just don't see it.
Until all the good stuff disappears.
Or the bad stuff gets too big.
But then it's already too late.
So make sure you always keep an eye on the bad stuff.
Make sure you do something against the bad stuff while it's still small.
No matter how good the good stuff is.
Because the bad stuff will always be around.
And it might destroy the good stuff.
Sooner or later...
