For everything there is an appointed time, and an appropriate time for every activity on earth:

I decided to carefully and thoroughly examine all that has been accomplished on earth. I concluded: God has given people a burdensome task that keeps them occupied.

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.

Do not be rash with your mouth or hasty in your heart to bring up a matter before God, for God is in heaven and you are on earth! Therefore, let your words be few.

Do not curse a king even in your thoughts, and do not curse the rich while in your bedroom; for a bird might report what you are thinking, or some winged creature might repeat your words.
