Почему люди живут в альтернативных домах ?

My biggest dream in life is to make a round-the-world trip. it seems to me for this is worth a lot of work and live in general. i plan to work and travel at the same time. it's so wonderful to walk through the places about which jules verne and kipling wrote. i understand that i will have to sacrifice friends and family. but i think that they will understand everything. perhaps in traveling i will rethink my life, start thinking differently, change my values. travel makes people better and richer.
