== Example: A teenager == 

I want to model a teenager. I hope to use this model to help teenagers grow into happier, more successful human beings. I know this is a huge idea, as everyone has a different idea of success and happiness. However, I am certain I can choose the right variables and create a model. 

Imagine I had a model of a teenager. Right now, I'm thinking of the following variables: 

# physical health (1 to 100)
## exercise
## sport
## diet
## sleep
## substance / smoking use
# mental health (1 to 100)
## academic engagement
# emotional health (1 to 100)
## mood swings
## manage emotions
## emotional intelligence
# meaningful social connections (1 to 100)
# family stability (1 to 100)
# environment safety / stability (1 to 100)
# meaning in life (1 to 100)
# active in community (1 to 100)
# meaningful goals (1 to 100)
# fun / laughter (1 to 100)

I create a few models and then I design a test for the teenagers. I interview them a few years after they graduate and ask them if they are happy and successful. Would this be a good test?
