It’s the best financial advice, covid is the marketing keyword to remind you, if you don’t spend every last penny in the wallet, you can never have a chance to spend that again. Spend until you drop you plebs!
Not to be rude, but this is the advice of someone who has little sense when it comes to money. The reason that I like saving and investing is because it removes a lot of stress from your life. Money does not buy happiness, but lack of money can leave you in a very sad situation. Being in debt can be very detrimental to your mental health and this could end up taking years off your life unless you get it under control. Learning how to make your money earn more money is one of the most responsible things you can do in life - there are many traps out there designed to lure people into wasting money on unnecessary junk, so please be more wise about your future.
