Others:
Warehouse management - not just driving a forklift. Look up the organization WERC and find the local chapter and attend some meetings. If you can manage a warehouse you can make decent money, though hours can be crazy.
Whatever field you do want to do, join the national and local branch of its professional association. Attend the meetings and network and get to know what the field is like and what opportunities there are.
