Tough tough tough

The world is not bad
The world is not good;
The world is the world;
A very tough place;
Good and bad;
You must be tough
To survive in the world;
If you are weak,
The world will swallow
You really have to
Be as tough as
Tough skin;
That is how to survive
In our hard world;
Be tough in a tough world.
Be tough, tough, tough.
Be tough in a tough world.
