Undergraduate / "Why I chose to major in Nursing" - Help on a cause and effect thesis [6]

Just starting the intro and the thesis. The teacher gave us topics and I chose,Why I chose to major in Nursing. The audience is adults. I just need to know if the intro and the red font thesis sounds good enough or am I way off?? Thanks for any input:)

Twenty years after high school, now I know what I want to be when I grow up. A nurse!
After high school I married into the military which moved us around alot. I managed to get schooling and job placement as a dental assistant. Rewarding as a career as that is I knew there was always something more,something better. With a better late than never attitude I have decided to peruse my degree in Nursing.
