No man is an island.
The enmity of the wise, rather than the friendship of the fool.
Fortune favors the bold.
People who live in glass houses should not throw stones.
Hope for the best, but prepare for the worst.
Better late than never.
Birds of a feather flock together.
Keep your friends close and your enemies closer.
A picture is worth a thousand words.
There's no such thing as a free lunch.
