Despite travelling alone, Schoultz says she never finds herself wanting for company, especially as she usually stays in hostels.
However, this means her itinerary is constantly expanding.
"I just meet so many people who have been to so many amazing places and I'm like ok, that's on my list now — and the list is just growing."
The highlights of her trip have included hiking to the "stunning" Machu Picchu ruins in Peru and experience Rio de Janeiro's Carnival with a friend — and meeting some new ones along the way.
"I was really lucky because I met a local in a supermarket, while waiting in a 40 minute queue. We spent the whole week with this group of people, gong to all the local block parties — we didn't see any other foreigners."
Initially nervous about travelling to South America alone, Shoultz's granny sewed pockets into her bras before she left, so she could keep her money close to her.
The young traveller also stresses the importance of keeping track of spending.
"That's been a good learning curve, to always have a budget and always write down how much I spend."
While millennials are often criticised for prioritising travel over saving for a house deposit, that's something she says she'll get to later.
"I kind of figure that I'll get to that at some stage, but right now this is more important to me. This is the one chance in my life I have to travel by myself, to be entirely non-reliant and completely free."
