Inflation is coming you guys in the U.S.  Best to invest in education / specialize in education / become indispensable or pick up a trade for backup / invest in real estate.  In some ways it is good to stick with free.  I get that, because you'll want money to  make money.  You need to get out of debt.  The big thing about Mewing is it takes so much time.  Paying an orthodontist can be worth it, though, because you are able to leverage better earnings.  You'll just want to specify exactly what you want done.  If they fail to deliver, ask for your money back.  However, that is a booby prize.  Losing is not great.  Better to find someone who specializes in what you want and trust them to get the work down.  Take it from someone who did a watered down version of Vivos.  The results were terrible.  Go for the best.  Pay them and just move on with your lives and you will be happier.  You need someone compassionate and who knows what they're doing, who will integrate your concerns and is educated.  If you find someone like that, please do share their name.  We can all fly out there and just relax and move on in life.  Dr. Derek Mahony in Australia is one such person.  I wish I could just fly out there.
