We need to work, yes. But not putting in “labour” (much effort) for the purpose of “getting rich” as this verse warns against such ‘common man-made (own) wisdom’:

“Labour not to be rich: cease from thine own wisdom.” (Proverbs 23:4)

It is good therefore to work sufficiently (and “not” overly) & be content in whatever state we are in.

P/S:

Notice that the world often teaches the exact opposite namely:

‘work hard to be rich’

Or

‘work till your bank balance looks like a phone number’

Or

‘while others are sleeping, I am still working’

Etc.
