Higher education in the united states is an optional final stage of formal learning. Many people do not participate and many are better off for it.
I am surprised at the number of kids that do not want to continue education.
Some call it tertiary education or post-secondary, I personally am a college student persuing a PharmD 
That is great and I am sure a lot of hard work.
A doctor of pharmacy degree is an 8 year program all-in-all
I am sure it would be worth it in the end.
Absolutely, it's been a lifelong goal of mine to become a licensed pharmacist. 
Good luck! I am sure it will be awesome.
