Summer is just around the corner, and, for many college students, their summer plans include filling one of the 1.5 million internships nationwide. For many students, this is their first venture into the private sector.

Diving into the unknown world of open offices, regimented meetings, and ungraded work can be quite intimidating. A well-done internship, however, offers fantastic experience, essential contacts and possibly a post-graduation job. So to help out anyone taking their first (or second or third…) internship, I’ve compiled a list of six essential tips:

1. Work hard.

This ought to be obvious. As an intern, you are new to a company. The fastest way to build trust with your peers and garner the faith of your boss is to be diligent. Volunteer to do the “dirty work” of grabbing the mail, stuffing envelopes and other tasks most everyone feigns to do. Be willing to stay half an hour late if the situation calls for it. Arrive early; be industrious.

2. Be bold.

It is intimidating being the “new kid on the block.” It’s common to feel unworthy while stepping into bosses’ offices or putting time on people’s calendars. But the team around you wants to see you succeed and actually needs you to be willing to step into uncomfortable situations boldly to do your work well.

3. Don’t gossip.

As a new hire, it is natural to want to foster friendship in the office quickly. If peers are talking about other team members, it’s tempting to join that conversation. But as the low man on the pole, you do not want to be on the gossip train. Others will recognize this and respect you for it.

4. Be a great team player.

Go the extra mile to be a fantastic teammate. If it’s someone’s birthday, write them a card; if it’s someone’s anniversary at the company, bring donuts. Always be aware of how you can make a positive team impact.

5. Think long-term.

As an intern, your time is capped. You know the date when your internship ends. Do not let this stop you from thinking long term.You were hired for a reason and your work has impact; make the necessary preparations so your work will continue to positively influence the company even after your departure. This futuristic attitude is what separates good interns from great ones and helps to maintain relationships with the company.

6. Keep in Touch

At the end of your time, thank everyone you got to work with. Keep in touch through LinkedIn, over email and even via Facebook after you’ve left the internship. Leave on great terms – you never know if you might come back to work there again!
