Get some references before you leave: it will make all the difference. Try and get your boss, your neighbour, or whoever you have done some work for to sign up to Working Traveller and get them to leave you a reference for whatever it is you did for them. Go work for free in your local hostel, farm, anywhere that would be happy for the help and a profile on WT. Once you have a reference and case study, you can add pictures of your working and rank high in work searches when hosts are looking for your skills. All this can be done on a free account as you can contact up to 3 hosts a week on a standard membership. Once you are ready to leave, upgrade to full membership for €10 and year so you can contact as many hosts as you want a day.
Work on your skills that will get you to work on your travels. They may be part of your career plans or maybe not. 10 good work references from 10 hosts around the world doing anything will help you get a job when you get back home as it shows you are willing to work hard, something your degree does not show employers.
