Full Question I’m a senior in high school. I’m in some clubs and play LaCrosse. But I just don’t know what I want to be when I grow up. How do people know these things? Dave, age 17 Dave, some people know at a young age what they want to be in life. For others, it takes time to figure out. But you will figure it out if you spend time looking for answers. I recommend taking a career test. This will give you many career options that you can narrow down. Ask your school counselor or read Do What Your Are, by Paul D. Tieger & Barbara Barron. This is a fantastic book. I use it with my students. You can probably find it at a library or any bookstore sells it. Good luck! Mrs. D.
