meaning of a paragraph

[Learning_English]

The full saying is 'It's an ill wind that blows nobody good', the emphasis being 'it is indeed a harsh wind if it damages everybody'.

It was already proverbial when recorded by Thomas Tusser in Five Hundred Points of Good Husbandry (1580) as 'It is an ill wind turns to good' (... if it makes nobody turn to doing something worthwhile), a version that makes better sense in implying that misfortune brings out the best in people.

Could anyone explain what does (if it makes nobody turn to doing something worthwhile) mean in the above paragrap?
