I agree with Cat Doc.
You are one of hundreds of faces they see. I have had kids come up to me and tell me I had spoke to them at another career fair and I woudl never have recognized them. If you need a "confidence booster" you shoudl look up your local "Toastmasters." It will build your conversational skills, public speaking skills, build your confidence, and introduce to others in the same boat in your community. It is a great resource that many young folks ignore. Its a $20 fee to join and then $27 "dues" every six months which pretty much covers the food at each meeting. So that equates to $47 for the first six months and $27 every 6 months thereafter. I was a guest speaker at a meeting about dealing with hostile folks and was shocked to see who were members...many who would be good people to know including the police chief, a state senator, TV reporter, radio DJ and several business folks, all there to participate and learn. I highly recommend it!
