time to break out of your shell
Be enthusiastic with your life.
If you look around you, you'll notice that the people who are the most attractive and charming are often the people who are the most enthusiastic with their lives.
As humans, we're naturally drawn to people with "high-energy" - people who're full of life and not afraid to be passionate.
Passion is sexy - in both men and women.
Think about it. Would you rather date a woman who talks in a monotone and never wants to go out, or would you she enjoys in life?
Now...pretend you're a woman. Would you rather date a sexy, adventurous man...or would you rather date a boring geek?
Enthusiasm is sexy, period. So if you're a couch potato who stays at home all the time, I strongly encourage you to go out with live life.
