In a letter bank, the letters of one word or phrase are used - and repeated as necessary - to spell a longer word or phrase. For example, IMPS is a letter bank for MISSISSIPPI. Only the letters I, M, P, and S are needed to spell MISSISSIPPI.

Using only the letters in the phrase NO SWEAT, can you spell out a 4-word proverbial phrase? The letter count in the four words is 5-3-4-3.

HINT:
The phrase has to do with prudent living and frugality.

Answer:

WASTE NOT WANT NOT
