If you have 600k$, you should be able to get a passive income of aprox. 2,500$ a month or more on avarage from it. If you are single, you may cancel your flat, put your things into storage and use your parents or a good friend's home as your official address, buy a small used camper-van (not too old) and start travelling. I doubt that you will need all the 2,500$ a month. When you feel that you have travelled enough or just noticed that you did not like it, you may resell the camper-van and continue your life as usual. -- I did something similar myself in Europe, except that I worked a bit from the camper-van and after some time become sort of semi-nomadic (travelling in summer and dwelling in winter, short trips in spring and autumn).
