ok,
some more information:
I'm 27 and renting a room in a house with 4 other people (so I can easily find someone who want to rent my room while I m away and take it back when I come back), living in Brussels, Belgium.
concerning my job, its a bit all at the same time: i want to do a trip, and i'm not so interested anymore in my current job.
My boss will never give me a year off work i'm afraid, but indeed I can always ask for it. I will not tell i quit, but i will tell that I am in a preparation of a big journey because i want to see the world. I will see if we can make an agreement or something like that, I don't really know, its my first good and serious job and the first time I quite one.
It's better to obtain some statusses here in belgium for holding all the privileges from the social security, but after all, my journey is what has the priority.
I am pretty convinced by now that i cannot stay here in belgium and keep on working without doing a big trip.
countries I really want to visit: none.
it will be the west coast of africa, or the east, doens't really matter.
My plan is to travel for 2 or 3 months, and I woud like to do some volunteering for 2 months, and then ride back.
So ride to cape town and back, will be a little bit too far, but it is not something i delete from my options.
I read some things about the visas, but I cannot figure out exactly how much it will cost average / crossing borders either. a carnet de passage i already took it in mind, but the cost itself is only 200€ or something like that (not including the deposit, but you get it back once back in Europe)
surely, in the 2 following months, I have to make up the plan, so decide wich countries etc...
so, let me know if this a foolish think, or something that might work out.
note: and if it's foolish, I'm afraid there is no way back
