You shouldn't speak or act too quickly today because you are going to be around people who are quick to judge: and slow to listen. Not only could they misinterpret your goals, they could start talking to other people and spread news or gossip around that isn't accurate. Also, while your confidence is healthy and well-managed, it could come off as arrogance if you are not careful. You need to know your audience: and then you can avoid saying things you'll regret.
