Help me think of some slogans on the construction site, which are about extravagance and waste, diligence and thrift. I hope everyone can help me!

Waste is not done in small quantities, and saving is not done in small quantities.

Save and reduce costs, save and improve benefits.

Oppose extravagance and waste and save limited resources.

Diligence and thrift will benefit future generations.

A needle and a thread are rare; It's a pity to throw one brick at a time.

Save a drop of water, tighten the faucet, save one degree of electricity and turn off the lights.
