I'd get my teeth fixed. Straightened, overcrowded wisdom teeth pulled, whitened (after years of mh related neglect).
They're a constant reminder of a really shitty time in my life. They used to be basically perfect, straight and white with no fillings (I still have no fillings but awful gums). Now they are awful. They need multiple hygienist appointments to get them properly clean and get all the tartar off them so I can get them back into a reasonable state. But being on minimum wage in the middle of a pandemic it's not going to happen any time soon.
If there was any left over I'd go on holiday to Greece and go on lots of history tours
