Unfortunately, there doesn't seem to be much substance here; it reads like a high school guidance counselor's pep talk. If you are seriously interested in entering engineering there are several good books available:

A fairly recent books is Studying Engineering, http://www.amazon.com/Studying-Engineering-Road-Rewarding-Ca... , unfortunately even it is eleven years old.

An older one I read more than 20 years ago, but is very readable and has a lot of useful information, despite its age, is Eric Laithwaite's Invitation to Engineering, http://www.amazon.com/Invitation-Engineering-Eric-Laithwaite... .
