So what happens if you don't learn a lesson in life?
You repeat the same mistake.
And every time you make that mistake the results get uglier and uglier.

It is good to take some time and figure out why things went to pieces.
If you do not, and you happen to repeat your folly, you will have the lead role in your very own horror show.
You will be lucky if you are the victim. Most likely, you will be the monster that leaves a trail of human wreckage.

Just some light and pleasant thoughts
