It goes like this: You have to tell your favourite saying and write a short explanation why you think it is your favourite, if given the author.
Mine (it's three, I love them all):
1. "What don't brake us, make us stronger." (The Mailman)
I've recently heard The Mailman saying this in his Retirement Press Conference. When I fail something or get disappointed, I always think: Next time you'll do it better. Well, actually, to make it gramatically correct, it should be "what doesn't break us, makes us stronger", but Cowboys talk a different way.

2. "Man does not live by bread alone." (Deuteronomy)
You should not only fix at one aspect of live, but do many things together. Means you cannot just live with NBA Live or Basketball, other aspects are not less important.
3. "It's not your enemy who gets you, it's always your own people." (Nas)
I really have more discussions with my family as with others. Because you know them better than other people, and they know your weeknesses and how to disappoint you.
