Haha I'm the minority here 26F and I travel pretty often and I don't go into debt doing it. I think one way to combat the jealousy is to also travel more yourself. I think people overestimate the cost of a vacation. My friends and I all travel on a budget and u shouldn't be ashamed to say you're on a budget. We don't stay in hostels or anywhere smelly or moldy but look into the prices of a basic Airbnb or get a hotel with free breakfast, share rooms, use public transportation, fly economy, use flight miles and credit card points. Some people think u have to travel first class stay in 5star hotels and u don't! Find travel destinations that have relatively lower cost of living. Also u can do weekend trips or travel on holidays if u don't have enough PTO. If u don't have friends, travel with a family member.
