identity status and psychological well being

this topic relates to my EE topic in psych which talks about the psychological factors that cause juvenile crime. so while researching i came across 3 with this interesting thing. it was said that if teenagers report a greater similarity between their ideal self( what they hoped to become) and their real self are less likely to commit a crime. whereas teenagers who lack this similarity are said to be stuck in a foreclosure and are more likely to commit a crime.

what does this similarity between the ideal self and the real self do to our psychological well being?..when our ideal self agrees with our real self we tend to have a higher self esteem. for example, if my ideal self wants to be a doctor and my real self is working towards becoming one and is doing well.then i can be more confident. whereas if my ideal self wants to be a doctor and my real self is doing extremely bad in biology at college level, then my confidence level can drop.

but does this difference in the self show the instability in ones identity? am i two different people while wanting to be a doctor and doing badly in biology?if that is so then ones identity is constantly reformulating. it exists differently in different situations.
well..i completely disagree. i believe that our identity exists the way we want it to exist. it takes shape on the basis of what we believe. if the teenager believed that he or she is a doctor then he is. if he believes he should commit a crime then he can be known as a juvenile delinquent. .
