Wow, informative must for career path
Format: Paperback, Format: Paperback
Great resource for any student, young or old. Solid advice and support continues with bonuses after you read with links and resources. Even some one on one with the author, worth much more than the initial cost of the book. Very informative and uplifting. The author wants to make your career choice path easier. A must have for college bound students. It’s like finding a treasure map to all the right ideas! Front to back a super read. I purchased the physical copy and plan to share it with a high school student.
