Kind of a spoiler alert- They always come back- Harry Potter Year 2

He grasped it around the ankles and turned it upside down.
 "This is what you have to do," he said. He raised the gnome above his head and started to swing it in great circles like a lasso. Seeing the shocked look on Harry's face, Ron added, "It doesn't hurt them - you've just got to make them really dizzy so they can't find their way back to their gnome holes." He let go of the gnomes ankles: It flew twenty feet into the air and landed with a thud in the field over the hedge

In this paragraph Ron and Harry are deGnoming Ms.Weasleys garden. Ron explains that the gnomes will come back even after they are launched out of the garden. This made me think of problems in life. If you just push them out of the way the will come back. What you need to do is kill them and zap them out.

Its like the gnomes they will get dizzy and for a while not be able to find their homes but dizziness doesn't last your whole life. They will find their home again. And i know this may sound intense but if they could just zap them with their wand, the gnomes wouldn't be able to come back. And the worst part is if you don't deGnome the garden regularly they will reproduce and overtake you whole garden.

So like if you just let a problem sit there in the air, just like all your other problems the will start to pile up and  become overwhelming.
