if you can’t travel anywhere this summer, try to discover a new place from where you are by reading. choose a country or a city and read novels and short stories that are set there, look at a map while you do that and trace each character’s way. find recipes of typical meals and cook them for yourself, and listen to music, classic, folk or contemporary from your daydream travel destination. read up on the history of that place or find interviews with contemporary witnesses to listen to or watch online. check out if there are any documentaries on youtube (usually, there are a ton of them), maybe watch one or to film classics from the country or city you chose, or just watch a ton of trailers to get a taste of the atmosphere of the cinema of a different place.
a summer job or an internship, even if chosen voluntarily can make the time between june and september feel dull and not very relaxing. simply not being able to afford travel might feel numbing too, so don’t stress yourself about dedicating every minute you can spare to this if you have trouble focusing. just don’t let yourself be stopped from discovering something when you got that wanderlust but can’t wander.
