Say what's on your mind! Speak what's on your heart! Sometimes I rub people the wrong way with my bluntness, but I'd take real over fake any day. I'm not really interested in formalities and niceties, and that shows in my interactions with people. Sure, some people don't understand me and may sometimes think I'm rude, but most people really appreciate it (especially guys). It's how I develop strong and lasting relationships with people. I've seen a lot of superficial relationships, and it's because people hold back what they really want to say. I've had people envious of the relationships that I've established, and it's only through my inability to be anything but authentic.
So when you speak, BE FOR REAL!
