Coming of age is never the same for everyone. If you can honestly say that you never went to a phase where you rebelled, whether secretly or expressly, then you are definitely one of the few people who did not experience any rebellious streak during your teenage years. But, for most of us, adolescence is probably a phase where we tried all sorts of ways to challenge our parents and explore things that parents normally tell us not to do. Yes, it can be a problematic part of life, but in the end, all will work out once you come of age and realize that life is more than what you think you know. These 75 photos of people before and after their rebellious phase show us just how much a person can change as time goes by.
