Simply put - if Depp never THINK and ANALYZED his goals and followed the "correct" path, he obviously would not have become the person he is now. There are MANY ways to success and a formal education isn't necessarily the only way. With that being said, formal education is USUALLY a pretty safe path to "success" but it's more important for the individual to customize and forge his/her own journey.
For Johnny adept, dropping oily for school was the right choice. He was able to get a jump start on his career and he did not have to worry about racking up thousands of dollars in debt for a degree he was not going to use. His talents might have
been wasted if he stayed in school.
Dropping out of school isn't for everyone, but in Johnny Depp's case it certainly worked out. He's more than financially stable and is very well known. Most people/dropouts won't have the same type of success, but by the same token, school isn't for everyone either. Anyway, with GED programs and online colleges people who drop out and can always decide to go back to school later on.
Yes, Johnny Depp made the right decision to drop out of school. It is pretty obvious that despite the current tabloid drama he's involved in, he's had a pretty succesful acting career. Johnny Depp is one of those rare people that have the drive to succeed no matter what, and a high school diploma could not have gotten him any farther that he's gotten today, in his chosen profession.
Yes, Johnny Depp made the right decision dropping out of school because he became a huge actor. If he failed, it would be a different story. But Depp has proven that he is one of the best actors today, and therefore his path to becoming a great actor is justified.
