Was thinking about mine and thought it'd be interesting to know other people's especially since I might have some of the same bad habits without having picked up on it.
I have two:
1) I drop my right hand every time I throw my jab - suprisingly enough posing like super man in the ring hasn't given me any super powers!
2) I try to be tall against taller opponents - it really is time to accept the fact I'm a short a*** and get over it!!!!
So now you know mine .........
