I'm working for one more year (and a bit), banking as much as possible, leaving my job then doing a wee mini-tour of Southern Europe around the Med (WWOOFing - free food and accom. for labour on farms and stuff).
I'll gradually work my way round to Spain, where i'll practice a bit of the language, before flying out to S. America (probably Buenos Aires). Once there i have several longterm voluntary placements (future career related) in mind around the continent, with the rest of the time spent leisurely touring between them.
Once all the pre-arrangements are completed, i'll see how much money i have left, how much i want to go home or whatever, and decide what to do.
That's the very provisional plan.
