Every year there are more and more people in the world.
If there are more people, we will have more friends every days.
If we need more friends need to know more see the world.
If we see the world, will need more money to travel.
If we need more money, we will need more work.
If we will need more work, we will find more work.
If we will find more work, we will be more difficult to find work.
I we will be more difficult to find work, may not travel so much.
