Think about the future

Lately, I often think about what occupation I want to enter. I want to engage in conservatin the environment. However there are many occupations on conservation the nature. So I wonder what occupation agree to my tastes... I like chemistry, but I haven't confidence in my ability about that. However I want to be a person who analyze and measure chemicals that affects the environment.
So, I aim to be a Environmental Certified Public Measurers first.
