For financial planning, it would depend on what role in the industry you would be entering. If asking specifically about being a financial planner working with clients, this is more of a commission based business. Some firms may offer a salary in exchange for less compensation, or start someone with a salary that may phase out once they are established with a book of business. I would say the range is too wide to define.
For nursing, it mainly depends on the region, shifts, experience, and educational background. There are nurses earning $20/hour and some $80/hour, depending on the above factors.
But apart from the income, please keep in mind that working with people to help them live their dreams is a wonderful way to spend your professional life. People are just so thankful to have an advocate they they know is looking out for them.
