You may have debts to pay. Test these three conditions quickly and often. Find out what you can earn. Interview several sources and expect to find a spread. Ask about these discrepancies and always ask what you could do to increase your earning power if you decided to pursue that occupation.
Employers are less likely to exaggerate than individuals.
Use published salary surveys as a point of departure, not as the last word. The occupation isn't right for you if you can't afford to work at it. Get part-time or volunteer jobs at the entry level to verify your aptitude for the work and compatibility with your future coworkers and clients. Such positions amount to self-guided internships. Internships are effective and respected methods of preparation for a new career.
