MLC is the "major" identity crisis for those going through it. It's not just going back and doing it one more time, but they are trying to find themselves because of being emotionally stunted at a very early age. They need to grow up and leave the teenager life behind and accept that they are getting older and mortality is looking them in the eye more and more each day and that you can't go back and do it one more time at the fountain of youth. This is why you see them wearing many different masks during their journey because they are still trying to figure out who they want to be.
It's very sad and I do feel a lot of empathy for anyone who is going through the crisis because they do tend to destroy a lot as their travel their path to maturity.
