This is a great question. The answer is no. School isn't necessarily for everyone - but if you truly want to become an Actor or Actress it is something you have to be willing to study. The more you know about people, the more you understand about how to access your emotions and work on a character the more likely it is that you will succeed. Acting is a really tough industry to be a part of, and sometimes it's helpful to spend some time studying to decide if it's truly what you want to do. I went to university to study film for 2.5 years but left early because as exciting as the program was, I didn't feel it was helping me grow in the ways I needed. I then pursued a different approach to my studies, I went to intensives for acting, studying for 1 week - 4 weeks at a time, working tirelessly with really phenomenal coaches. I went to weekly classes to learn and watch and understand what it took. I think at the end of the day it is up to you to decide whether or not post-secondary education is for you, but no matter what you want - if it's your dream, work for it, and be willing to work hard. The best advice I can give - is that no matter which you choose, educate yourself - learn about people, learn about behaviour, study people and mannerisms, understand yourself the best you can.
