Mentor and first job for an 18 year old looking to get started.

[Antonio Jimenez]

Hi everyone, Im Marco, 18 year old looking into real Estate. I was wondering how people went around getting mentors, like do you ask someone hi could you mentor me, or is it over time finding someone and working with them, which brings me to my next point, what would be a good first job to get knowledge in Real Estate. Keep in mind i will begin my first year in college to get into med school, but want to buy a four plex before next year. 

Any tips or advice would be wonderful.
