Actually a traveller needs to have a rich heart, great exploring mind, enjoying the travel with abundance patience, that money is much a part of travel, though being rich is by choice.
Being basic rich is important. you may say that one can stay in budget hostels but transport takes up cost.
so when it comes to travel international. yes you need money.
either you can choose a job that offers that money to you.
Absolutely not....there are shoe string budget holidays too; affordable homestays could be another option; there are also sponsored trips when you participate in online contests 😊
Not all you, you have to be rich to relax in 5 star hotels or if you are craving for luxuries more than travel than you have to be rich, for traveling you just need guts to step out
