Studies have shown that the ability to allow yourself to be vulnerable correlates with your ability to be happy and successful, so maybe it's worth becoming a little more comfortable with being a little uncomfortable?! 

A feng shui tip to strengthen your ability to show others who you are and express yourself: frame a piece of your own artwork, display a private collection, poem, or even a dream on yours jotted on paper in a public area of your home. Your willingness to put even a bit of yourself on display is a small but huge step toward being OK with the feelings of insecurity that come from being "on-display" and the vulnerability of true self expression.
