Man's extremity is God's opportunity. Eat to live, not live to eat. Speech is silver, but silence is golden. You never know what you can do till you try. No man can serve two masters.
Opportunity never knocks twice at any man's door.
There's no place like home. A fair exchange is no robbery. Every cloud has a silver lining. You never miss the water till the well runs dry. If you lie down with dogs, you'll get up with fleas.
