Let's categorize each item as either a paradox or not a paradox:
Paradox:
- Everyone is equal but some of us are more equal than others.
- "The more choices you have, the less satisfied you are with each one."
- You must spend money to save money.
- The bird swam deep under the water. (This can be seen as a paradox if one assumes birds do not typically swim deep underwater.)
Not a paradox:
- There is no problem that cannot be solved with communication. (This is more of an optimistic statement rather than a paradox.)
- Even though I was tired, I stayed awake. (This is a statement of contradiction but not necessarily a paradox in the philosophical sense.)
So the completed categorization looks like this:
Paradox
- Everyone is equal but some of us are more equal than others.
- "The more choices you have, the less satisfied you are with each one."
- You must spend money to save money.
- The bird swam deep under the water.
Not a paradox
- There is no problem that cannot be solved with communication.
- Even though I was tired, I stayed awake.
