Well, I started out in Long Term Care nursing and didn't feel satisfied, I tried a few different facilities and never felt really happy. In fact I would dread going in at times and felt stressed out to the extreme.
I had a dream job from when I was in nursing school
and precepted with a home health nurse and knew right then that I loved that type of job and that was what I wanted to do! I had applied to work with a local agency that visited people in their homes and I was denied. After a year I tried another agency, they also replied that they were not hiring, I just kept emailing her my interest every six weeks or so and after eight months I was given an interview.
I got the job and have been so happy ever since. I really like this job. I feel it is a good fit for me, and I'm a good fit for the job. I knew that I wanted to do this job, I just didn't know how much I would enjoy it, and how good I would feel about it. Its a total turn around from my other jobs that I would daydream about calling in sick to, or start feeling icky when I knew it was near the time to go to work. I feel like this new job is just a natural extension of my natural personality, and is a natural easy thing to do. I don't feel stressed out before work, or after. I feel like I am getting paid to do what I love to do. I know I wouldn't have been prepared for this or able to do this without my previous experience though, so I guess I can't really knock those stressful hard jobs as being a complete waste of time.
I guess if you have a job that you think you might really like... keep trying, you never know.
