Don’t Talk About your Ex
Whether it’s positive or negative, talking about your ex sends a bad message to prospective partners. In a nutshell, you either seem like you’re not over him or that you’ve got serious baggage.

Don’t Make Snap Judgements
If he walks in wearing loafers with no socks, tragic facial hair, or has some other surface feature that turns you off, don’t assume he’s unworthy. Get to know his personality and concentrate on upgrading his look later.
