In Exodus the Israelites are commanded to observe Shabbat. In this week's torah portion they are commanded to allow the land to rest every seven years - Shemitah. While there are economic benefits to rest and renewal, there are also many economic fears. Nevertheless, mitzvot are not given based economic impact, rather based on soul impact. Although it is scary or challenging to cease creating, counter-intuitively it is precisely this cessation that creates a new version of ourselves.
