[habitual speaking errors]

My "to do list for habitual speaking error modifications" intentions are: be aware, self educate, institute mindfulness during communication and internal dialogue, and if found lacking do the necessary damage control as soon as possible.

[habitual speaking errors]

sounds like you already know, just by your awareness of this it should subside. my intuition is that maybe you have some disassociation because it is uncomfortable. sometimes i have an issues with this, if i make a mistake I might say "we did this." inversely, if something good I might say "I did this."  I can only speak for my self, but generally i think we all may do this to any uncertain degree.
