Have an Answer?
I invite you to consider the following ideas:
1. Interview at least 2 people who actually do each of these jobs. Ask them the following questions:
a. What do you like about your work?
b. What do you dislike about your work?
c. What are the job and advancement opportunities in this field?
d. If you had it to do over again, would you choose this field?
e. What skills and credentials are required to be successful?
f. Who else should I talk to?
2. Find someone in each field that you can "shadow" for 4-8 hours while they work. You will get to see what they actually do.
