Ecclesiastes 2:3

2:3 I thought deeply about the effects of indulging myself with wine

(all the while my mind was guiding me with wisdom)

and the effects of behaving foolishly,

so that I might discover what is profitable

for people to do on earth during the few days of their lives.

Ecclesiastes 11:6

11:6 Sow your seed in the morning,

and do not stop working until the evening;

for you do not know which activity will succeed

whether this one or that one, or whether both will prosper equally.
