If your relationship is going anywhere, you have to be yourself. When you're first getting to know someone, it's tempting to say what you think they want to hear, just to make things run a little smoother. Trying to impress her by faking or exaggerating parts of your life and personality might reap short-term rewards, but eventually it'll all come crashing down around you, which is why this is precisely one of the ways guys blow it. Sure, make your job sound a little more interesting than it is -- that's fine. However, pretending you're a high-flying entrepreneur to impress your girl just isn't right.
