||Building your resume is probably the most proactive thing you can do now!
Join some open source project as Orange_Cloud says or work on some filed that interests you much and try to come up with a paper on that field. If you are intending to come back to academia for MS or any higher education, papers may be greatly valued and your research on the field may give you more ideas. It may even impress companies that specialize in your field and may get you a job there. And of course, you can try to participate in Component competitions at TC and make money!
Am just in college 3rd year end now! Should be facing the full brunt of this economic downturn next year! :(
