Goal 4: Complete One Unassisted Pullup

I realize that pullups are second nature to many people, but I've generally just treated pullup bars as a fun place to play.  Despite having one in my kitchen, I still am unable to complete a full pullup unassisted.  So, my newest goal is to complete one full unassisted pullup (any grip) by my next birthday.  Definitely an attainable goal, but I need to stop simply hanging from the bar and start trying to lift myself up :-)
