It's not enough to know your biases intellectually. Even if I know how any or all of those biases apply to me, there's still a gap between my knowing as an intellectual exercise and my fully experiencing it such that I can act freely when the bias might otherwise direct my actions.

For me, the best practice that I've found at identifying and getting past biases has been meditation. Finding a teacher or a style that fits your biases is important to keep you motivated until the self-motivation kicks in.
