The Heart's Guidance

Ecclesiastes 2:1-3
 
1  I said in mine heart, Go to now, I will prove thee with mirth, therefore enjoy pleasure: and, behold, this also is vanity. 
2  I said of laughter, It is mad: and of mirth, What doeth it? 
3  I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what was that good for the sons of men, which they should do under the heaven all the days of their life.
