New King James Version (NKJV)
Ecclesiastes 1
17 And I set my heart to know wisdom and to know madness and folly. I perceived that this also is grasping for the wind.
18 For in much wisdom is much grief, And he who increases knowledge increases sorrow.
Ecclesiastes 2
1 I said in my heart, "Come now, I will test you with mirth; therefore enjoy pleasure"; but surely, this also was vanity.
2 I said of laughter--"Madness!"; and of mirth, "What does it accomplish?"
3 I searched in my heart how to gratify my flesh with wine, while guiding my heart with wisdom, and how to lay hold on folly, till I might see what was good for the sons of men to do under heaven all the days of their lives.
4 I made my works great, I built myself houses, and planted myself vineyards.
5 I made myself gardens and orchards, and I planted all kinds of fruit trees in them.
6 I made myself water pools from which to water the growing trees of the grove.
7 I acquired male and female servants, and had servants born in my house. Yes, I had greater possessions of herds and flocks than all who were in Jerusalem before me.
8 I also gathered for myself silver and gold and the special treasures of kings and of the provinces. I acquired male and female singers, the delights of the sons of men, and musical instruments of all kinds.
9 So I became great and excelled more than all who were before me in Jerusalem. Also my wisdom remained with me.
