I have two.
Leaving my home state to move across the country and be near a man I had, until then, only known online and by telephone. It was a BIG risk, and I don't recommend most people do such a thing, but for us it paid off. I was in a horrible situation, and he helped me get out of it. We've been married almost 16 years now.
Becoming a CNA again. I wondered if I could do the job, after injuries from a car accident some time back. I am struggling, but I am getting stronger, and it looks as if in the end I will be able to do it.
