When I was 17, I was honing my dance moves for stage challenge and attending netball practise.
I was stressing about my end-of-year exams, normal teenage stuff.
But for one British-Belgian teen, his typical challenges make mine seem a little bit ordinary.
Our World News Editor Kate Gregan explains.
Mack Rutherford is not your average teenager.
This moment marked the end of a challenging and sometimes lonely journey that took Mack around the world in five months.
Crossing 52 countries, the 17-year-old has become the youngest person to fly solo around the globe in a small aircraft.
"Trying to show with this trip that young people can make a difference, you don't have to be 18 to do something special, just follow your dreams and they'll eventually come true no matter what age you are."
The British-Belgian teenager - who comes from a family of aviators - set off from Bulgaria in March - at the age of 16.
He flew an ultra-light aircraft called a Shark - which can hit a cruising speed of around 300 kilometres per hour.
He encountered sandstorms in Sudan and spent the night alone on a remote Pacific island... but told CNN he witnessed some incredible sights.
"The Sahara desert was incredible, Kenya was incredible, I was able to fly over the national parks and see all the animals, Myanmar, when I flew over Burma, that was incredible, jungles on the mountains and actually flying over New York was actually amazing."
Solo flying, and breaking records doing it, runs in Mack’s family.
He was at the controls of the same kind of aircraft that his sister - Zara - was piloting, when she set a record earlier this year.
In January, she became the youngest woman to fly solo around the world at the age of 19.
Mack says he couldn't have done it without her.
"When I was 15 I got my licesnse and was the youngest pilot in the world at that point. Then when my sister flew around the world I thought 'wow that's actually something I can strive for and achieve' and so I also decided to work for it, so she really was an inspiration for me."
The flight took him through the African continent to India, China, South Korea and Japan.
He crossed the northern Pacific to Alaska - and headed down the west coast of the US to Mexico.
He headed north again through to Canada, before ending his feat in Europe -- but this doesn't mark the end of flying.
"I'm definitely going to carry on flying, I'm not entirely sure what place in aviation, just that I'm going to keep flying."
For now - it's back to being a regular teenager.
"After I've finished this I've got to focus on school and try and catch up as much as I can."
