If you are only acting modest because you don't want to come off as being too cocky, then you are not being honest! You're going to get some praise today -- don't feel guilty about enjoying it! When you do something remarkable, it's only natural for people to remark upon it and give you a round of applause. So why fight it? You don't have to ever worry about people thinking that you have a big head. They know you better than that -- give them some credit!
