@tchoupiloveu: Hi for everyone who saw that video and is interested and want to give a try i cannot stop you from doing that but i dont recommend it i was deeply amazed by people doing it but when i first gave it a try it i came back home without catching any train, it was a long wait for 10 day straight not doing anything felt depressed and bad questioning my self alot the constant stress of getting caught/ sleeping in the street i still managed to get some good memories but there is other way to enjoy the life go hiking, hitchhiking, travel with a bike anything is a good experience aslong as you go out of your comfort even the bad experiences make you better do what ever you want in your life and be happy with yourself and take care of youself and people around you
