What do I want

Many times this question pops up, especially of late because I'm graduating very soon and up to now I have no idea what I want to do.

In my previous post, I mentioned that I will be on holiday at Shetland. Best part is that I'll be on the bike most of the time. Everyone who knows me will know that I love nature. I also love to cycle. So this is a two in one and I simply can't say no to that! But there's something more to this trip other than these two facts. This is the first time, in a very long time, that I've found something that I really wanted to do. Here's why:

The taste of adventure - to a land unknown to me
My first outdoor adventure took place 4 years ago, when I hiked at Brecon Beacons, and Peak District for the Duke of Edinburgh gold award. I happily volunteered for it due to peer pressure without knowing what I was getting into. During the trip, thoughts of a fluffy pillow, proper food, dry socks, and a warm bed came to mind. I just wonder what would I think of in the next trip?
Also, I'll be on a 14 hour ferry trip from Aberdeen to Lerwick. My father said the North Sea is beautiful. I thought to myself: don't all seas look the same?

My connection to nature
I grew up with many pets around me, with National Geographic being my favourite TV show as a kid. I am fortunate enough to travel to see not only big cities, but the quiet and peaceful little villages of China, where the people were very close to nature - and I always envied them for that. I just watched a video recently on a lady who hunt for her own fish in the ocean. Most importantly, she observed the fish and whatever sea creatures which make up the ecosystem and 'appreciates that she knows where her food comes from and that it had lived a wild and free life'. And I liked what she said.
I saw nothing but sheep (and lots of sheep poop) during the last hike. I hope I get to see some wild birds, ponies, seals and otters (killer whales if I'm lucky!!) at Shetland. I may not get close to some of the wild life, but perhaps I can make a connection with the ponies :)
On a separate yet related note, I read a book called 'City of the Beasts' by Isabel Allende where the story is based at the Amazon. It's pretty spiritual and I think my connection to nature is a spiritual one.

How does this relate to what kind of work I want to do after I graduate? Perhaps nothing. Should I be working for WWF? That could be an option. Can I work in a chemical firm to make 'good' chemicals clean up the 'bad' ones? I want to do something that I'm really passionate about. In order to maintain my relationship with nature I should take care of it - like how you would do the same to your loved ones.
However, this is completely different from what my parents had in mind. Unless they don't mind their daughter being the head of an environmental NGO :)
