I went from a technical career path where I started in electronics technology (remember electronics? Fixing stuff instead of throwing it away

) then on to computers and taxation. The computer industry is continually in flux not because of the technology but because the business fosters and emphasizes the idea that stability is a bad thing. There's not enough a professional point of view in computers to feel like you're feet are on solid ground.
At least in nursing, I've had the feeling that there was always an expectation of support and a clear, and unmoving goal.
True, nursing technology is always changing. There are folks that fall short of their professional obligations, but for the most part, nursing roles are far better defined than anything I've seen in IT.
In short, I'm very glad I've made the jump. I think my last day in IT was very telling. Instead of being supportive of my decision to move to a nursing career, I was basically told to not let the door hit me on the way out. In IT, it seems that if you're not with them, you're against them. Who needs that kind of anxiety.
If I were to find nursing was not where I needed to be, I would be looking at any other field than IT. But I feel that I will be able to be a nurse for the rest of my life and continue to be fairly paid, respected, and above all a contributor.
Best wishes for a great career. And never admit you know anything about computers.
