Working hard or lasting at work?

I remember that when I was I child I wanted to be an ingeneer, then I realized that the numbers were not made for me... "I don't want to stay sitted in front of a screen in an office" I thought then. Then I wanted to be a medic, I wanted to help people. And finally I decided that I wanted to be a scientist, there was MY area.

In the future, I'd like to work in a laboratory. That's my current motivation (in fact, it is since I discovered that I really like to "make science" and that environment); I guess is something that calls me. I don't care if I don't become rich with science, if I'm happy with what I'm doing that's all what I need.

I wonder if I could travel a lot as I want being a scientist... but if I have the chance, why not? If we talk about work and studies, my dream has always been study or work in Germany. And if we talk about travel just for travel I'd say a lot of places. I really enjoy travelling and staying into the nature (as a good boy scout)

Looking forward, I'd like to take some kind of major in biochemistry. This because I want to follow a pure scientific way rather than being a typical Pharmacist, so I must go further in those skills.
