Ecclesiastes 2:1

Futility of Self-Indulgent Pleasure
I thought to myself,

2:1 “Come now, I will try self-indulgent pleasure to see if it is worthwhile.”

But I found that it also is futile.

Ecclesiastes 5:3

5:3 Just as dreams come when there are many cares,

so the rash vow of a fool occurs when there are many words.
