It’s true you should not waste money. It’s not the most important resource you shouldn’t waste. If you spend all your money on fun you can always go to work and make more money. Contrary to what most humans think, money is not an exhaustible resource. You may find yourself without money. A resourceful human will find a way to get more. It’s not money’s fault if you are not resourceful.
Time spent and words spoken are irreplaceable. You can’t retrieve a spoken word and a minute used is gone forever.
Do not wast words or time.
