What advice do you have for someone considering a career change?

This is my tentative plan:

1. Browse Indeed and identify jobs that I like the idea of having.

2. Identify skills for each and learn them at least superficially. In the process, I will get an idea if this sort of job that uses these skills is something I would like to do.

3. If I think I will like the job, dedicate time to develop competency in the skills and demonstrate it through projects at current employer. Then, apply to new job.

Another idea is to contact people who have jobs that I think I would like and ask them what it is like, do they enjoy what they do and why. But, I am not sure how to go about doing this.
