WHILE most girls her age have boys on the brain, globetrotting is Jessie Gretener's true love.
The Mountain Creek High School student is back home after a three-month solo trip through Europe and America, which she described as "absolutely incredible".
"I did lots of things I would never have thought of doing," the 15-year-old said.
From sampling pasta in Italy to using her black-belt skills to teach Swiss students taekwondo, Jessie enjoyed many experiences but rated welcoming in New Year's Eve at a rooftop party in Vienna as a stand-out.
"When they celebrate over there, the government doesn't organise fireworks, everyone buys their own," she said.
"It was insane, it was constantly going … it was so incredibly loud."
Although happy to be reunited with family and friends, she admitted she was struggling to come back to reality.
"It's very strange because I haven't moved on to another country or another place like I was doing when I was overseas."
She said she knew she wanted to travel from the age of seven and worked hard to make her first trip a reality, including taking on extra hours as a sales assistant to save money.
And she has reaped the rewards, with her three-month itinerary including Switzerland, London, Paris, Germany, Berlin, Italy, Austria and New York.
Jessie's mum Kylie said the trip had helped her daughter shrug off her shyness.
"She's grown up a lot … she's still the same old Jess but she definitely has a new confidence, she's a bit louder and crazier and more spontaneous," she said.
Jessie has already started saving again and is ready to get back on a plane at a moment's notice.
"I'm keen to head off in the next hour if I could," Jessie said.
