School counselors don't seem to be able to guide teens. Most teens have no idea about the wide range of career paths that are open to them. It takes longer to get into a career these days because of the need for school and working your way up the ranks. Many parents are too worried about this and put a lot of pressure on teens to make early decisions. Going to college without a clear career goal in mind can be very productive.
Students often learn a great deal about career opportunities while they are in school.
Working part time can be helpful in career decisions. Taking aptitude and interest tests can also be helpful in making a match between the child and various career paths. Relax and take your time. The time to be concerned is if their lack of focus causes them to withdraw from school or work and then waste time without getting any closer to an appropriate career path. If a cause is not clear to you, try to practice your listening skills and talk to the child about why this hatred has developed.
