In psychic reading sessions I see many clients who aren't thrilled with their jobs and are looking for something new that is satisfying. Each person in a session is different and I recommend different approaches. One approach is to take the Johnson O'Connor aptitude test.
It goes over a number of days during which you're tested for all sorts of things, including physical dexterity and musical ability.
From my perspective as a psychic I would not say this answers everything, but it's definitely a good tool. More than anything, on the inner energy level, it signals you are ready for something new and something true for work in your life.
