11 Everyone who lives ought to be wise; it is as good as receiving an inheritance
12 and will give you as much security as money can. Wisdom keeps you safe—this is the advantage of knowledge.
13 Think about what God has done. How can anyone straighten out what God has made crooked?
14 When things are going well for you, be glad, and when trouble comes, just remember: God sends both happiness and trouble; you never know what is going to happen next.
15 My life has been useless, but in it I have seen everything. Some good people may die while others live on, even though they are evil.
16 So don't be too good or too wise—why kill yourself
17 But don't be too wicked or too foolish, either—why die before you have to?
