There are also jobs that you don't "get" but choose. By that I mean, you wouldn't apply for this type of job in the traditional sense, but decide to invest your time on the work. A lot of artists have daytime jobs to support themselves while they develop their work, and possibly transition to a level where their art careers provide a sustainable living. Many professional artists who are interested in work related to the environment produce outdoor installations called Land Art. The landscape is a very important element of the work. Here are a couple of things to check out for inspiration.
The life path for an artist doesn't apply to a formula. People get there many ways. It's more about figuring out your interests and how much you want it. That takes time, experimentation, commitment to your practice. If that excites you rather than scares you, that's a good start! :) College is a great time to explore in an incubator. It gives you a support base and some structure that I found really helpful.
The two youtube videolinks show Land Art artists that have had projects funded by grants, fellowships, foundations. They didn't always have those opportunities but got there and it's possible! The advice I'd give to you is to allow yourself the opportunity to try things out and see what you really enjoy doing, making, learning. That part is really fun too!
