Ecclesiastes 10:2-4

New Century Version

² The heart of the wise leads to right,
    but the heart of a fool leads to wrong.
³ Even in the way fools walk along the road,
    they show they are not wise;
    they show everyone how stupid they are.
⁴ Don’t leave your job
    just because your boss is angry with you.
Remaining calm solves great problems.
