I'm an engineer who visited Berlin earlier this year and loved the city - it's like my home town of Melbourne, Australia which I love, but just MORE of it. I already had the itch to leave my 9-5 and go somewhere for an adventure, so when I got home I set about working out what I'd need to do to head over there and how much capital I'd need for about 6-months self sustained living in Berlin (came out to about $15,000AUD, thanks to the current strong AUD). I found out one of my close (engineer) friends was also looking to leave his job and do something interesting and exciting, so I've convinced him to come with me too. Succeed or fail, it really seems like we could be part of something exciting in Berlin! Any advice on dos and don't would be appreciated.
