When I grow up I want to be a social worker or child psychologist. What are the the first 3 steps I need to follow to make my job true?

mkcapen1's comments are good. I want to add a couple of items.

You can find an entry-level job as what's called a "Psych Tech" with just a bachelor's degree in Psychology. That sort of job can give you a lot of valuable experience, but it probably won't be exclusively in the area of child psychology and may not be the sort of job that you'd want to have for your entire career.

The steps that I would identify are:

1. Learn about the similarities and differences between a social worker and a child psychologist, and learn the differences within each of those professions. What sorts of social workers are there? (mkcapen1 is right about the differences between having a bachelor's and a master's degree in Social Work; a higher level degree is the door to greater professional opportunities).

2. Explore ways to strengthen the skills that are most important to those sorts of jobs. Good reading and writing skills are certainly always good to have, but other skills -- such as interpersonal communication -- are probably at least as important.

3. Be willing to review and even reconsider your dream job. You're still very young and are in a position to try on any number of different hats. While you're learning about possible future professions, you'll probably come across wonderful opportunities and possibilities that you've never even considered before.
