"Whenever you are asked if you can do a job, tell 'em "Certainly, I can!" Then get busy and find out how to do it." -Theodore Roosevelt
This is a statement I've heard a lot, though not always in this exact way. In the theater dept, our professors always stress to us that we need to help out around the building all the time. The point of this is to get word out that the theater students will help out anyone. The idea of it is, I would guess, to make us look better around campus.
I also follow this within the department myself. I'll volunteer for a job and then figure out how it needs to be done. As they say, confidence sells.
