'Turned' in the Bible

So I turned to consider [secular] wisdom, madness, and folly; for what will the man do who succeeds the king? Nothing except what has already been done.

So I turned aside and let my heart despair over all the fruit of my labor for which I had labored under the sun.

I turned around and directed my heart to know, to investigate and to seek [skillful and godly] wisdom and the reason for things, and to know that wickedness is folly and that foolishness is madness [leading to stupidity and recklessness].
