I decided when I was 20 years of age (I'm 26 now) that I shouldn't let what I do define me. And I shouldn't work for the bigger house or the nicer car, but I would start living and chasing this idea of being self sufficient and healthy (mentally, physically, spiritually, socially and emotionally). I quit my job with Union Pacific Rail Road in northern California to the dismay and confusion of some of my peers. I'm sure some people saw me as an ill informed youngster with a desire for passion yet no discipline. And in most senses I was, but I knew I was chasing something good.
Now I work full time in Southern California in a job I am more happy about but is by no means an "ideal" situation and I'm a lot closer to that dream. But then again I realize that such a task is not easily achieved but earned in longevity and discipline. I'm married now and my wife and I have the same dream, a simple life not being subjected to what culture tells us but by what makes our hearts whole. And we are constantly pursuing that dream.
Just my experience, life is always full of options and with jobs comes mindsets and ways of thinking (specially in your case). But ultimately it what makes you happy and healthy.
You have found the holy grail at such a young age. Good for you.
