Be seen. Volunteer for on-campus events that are organized by the university (find the person running something, and ask them directly if there's anything you can do to help them).

Always ask "Is there anything else I can do to help" after completing a task. Always be the first to start volunteering (show up early) and the last person to stop volunteering (stay late).

If you're a person of good character and genuine spirit, people will notice and talk about you. People will ask your help with bigger things. Repeat.

If you do this, you'll quickly get snatched up into some professor's research project and forced into grad school, like it or not. There you'll be forced to get your PhD and spend your life doing well paid research in something you're terribly interested in. Awful.
