One of my biggest mistakes as an intern has always been being too scared to volunteer. This is totally illogical, but unless I was 100% sure I could do an awesome job I wouldn’t even offer to try. I was always afraid that I’d mess things up, turn assignments in that were completely different than what was expected or just generally suck at something.
Other interns would volunteer and I’d think, “I totally could have done that!” It was a horrible feeling, but I learned to man up–erm, woman up–and just say yes. No risk, no gain, right? You have to be willing to take a chance on yourself (and possibly fall flat on your face). You really do miss out on a lot of opportunities when you don’t just say, “Hey! Maybe I can do that?” You can do it. So do it!
