How do people afford to travel internationally so often?

I’m currently in the middle of a 2 years masters program in my early 20s, I have a part-time job and I’m living in my parents house to save money. I get out once in a while to go camping with my friends or somewhere close (2-3 hours drive) to spend the weekend but I don’t really get out of the country.<br><br>Pretty much every other young adult posts daily on IG or Facebook about how they are enjoying their lives in Bali, the Maldives, Paris, etc. I’m so confused on how they afford it and if I’m overestimating how much it costs to travel. After my studies I’m planning on traveling around the world but it feels like I’m the only one in my age group who doesn’t get out of the country more than once per year.
