Get a FAA Class 1 medical done before you even talk further to your Dad, do a search in your city for certified doctors. Show the medical to your Dad and let him know how keen you are about this.
To become a pilot, is not an easy road at all, lot of studies all the time, keeping up to date with aviation info world wide etc etc.
