The one thing I would never do on a first date is try too hard to impress the other person. It's important to be yourself and let your personality shine through naturally. Trying too hard can come off as desperate or insincere, which will not make a good impression. Instead, focus on getting to know the other person and building a connection based on trust and mutual understanding. That's the best way to make a lasting impression and potentially get the hottest girl in school!
