There are many excellent, other-directed, and altruistic reasons to volunteer: you know that already. How about a cravenly self-serving reason? Volunteering can teach you to apply your excellent communication and problem-solving skills to the needs of an organization.
Whether or not you end up with a useful line for your resume, you can learn more about the contributions you are specifically suited to make to any kind of organization. Do you prefer working with people or things? Do you like to be out front and center with an organization, or do you work better behind the scenes? Are you better working with others one-on-one, or do you thrive in a team or group setting? Are you better at helping an organization raise money, or helping an organization figure out how to spend it most effectively?
Volunteering can help you get answers to these kinds of questions. Knowing these things about yourself can help position you for the job you want after graduation.
The Volunteer Fair takes place Tuesday, September 1, from 10:30 to 1:30 in I-Rooms A, B, C, at the Illini Union.
