I used MBTI in a similar way when I was younger. I identified strongly with the INTP type and wanted to become more outgoing and confident so I studied the descriptions of the ENTP type and deliberately cultivated some of those behaviours. It actually worked fairly well (though admittedly this was also around my 18th birthday so maybe it was just alcohol), nowadays I don't find it particularly useful nor the descriptions at all accurate but as a starting base for self analysis and improvement it's great.
