What is your purpose or call in life?

I'm still not sure what my purpose is in life; but I know the path I should and want to take. After high school hopefully, I want to continue here in Laredo for two years attending LCC perhaps. After I am done with my basics here, I hope to have my car by then and move in with my best friend over to San Antonio and rent out a apartment there. Both her and I are heading for the same university which is UTSA! We are both majoring in something diffrent, but, overall same school. There, I hope to study criminal justice to become a forensics and make my living from there on. I feel that crime is something that will never go away and when you are a part of a problem that needs to find it's solution, then you must be doing something right. Crime has it's call in life and my purpose is to help cure it.
